The principal executive office of the Issuer is 14114 Dallas Parkway, Suite 600, Dallas, TX 75254. Item 2. Identity and Background This Schedule is filed on behalf of MedCap Partners L.P. ("MedCap"), MedCap Management & Research LLC ("MMR") and C. Fred Toney ("Toney"), each of whose principal business office address is 500 Third Street, Suite 535, San Francisco, CA 94107. MedCap is an investment limited partnership, whose general partner is MMR. MMR is an investment adviser registered under the laws of the State of California. Toney is MMR's sole managing member. None of MedCap, MMR nor Toney has, during the past five years, been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors). None of MedCap, MMR nor Toney has, during the past five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction, as a result of which any of them became or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. MedCap is a Delaware limited partnership, MMR is a Delaware limited liability company and Toney is a United States citizen. Item 3.

Purpose of Transaction The acquisitions of Series C Preferred Stock and Common Stock described in Item 5(c) were made for investment purposes. Toney is a member of the Issuer's Board of Directors. Except as described herein, the reporting persons do not currently have any plans or proposals that relate to or would result in any of the following: (a) The acquisition by any person of additional securities of the Issuer, or the disposition of securities of the Issuer; CUSIP No. 225235209 SCHEDULE 13D Page 7 of 31 (b) An extraordinary corporate transaction, such as a merger, reorganization, or liquidation, involving the Issuer or any of its subsidiaries; (c) A sale or transfer of a material amount of assets of the Issuer or any of its subsidiaries; (d) Any change in the present board of directors or management of the Issuer, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (e) Any material change in the present capitalization or dividend policy of the Issuer; (f) Any other material change in the Issuer's business or corporate structure; (g) Changes in the Issuer's charter, bylaws or instruments corresponding thereto or other actions which may impede the acquisition of control of the Issuer by any person; (h) Causing a class of securities of the Issuer to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (i) A class of equity securities of the issuer becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Act; or (j) Any action similar to those enumerated above. Depending upon market conditions and other factors, the reporting persons may exercise warrants that they hold to acquire shares of the Issuer's preferred stock, acquire additional securities of the Issuer, or alternatively, may dispose of some or all of the securities of the Issuer beneficially owned by them. In addition, MedCap may receive stock dividends on the shares of Series C Preferred Stock that it holds. Item 5. Interest in Securities of the Issuer (a) MedCap beneficially owns 7,381,440 shares of Issuer's Common Stock and 173,438 shares of Issuer's Series C Preferred Stock which are currently convertible into 17,343,800 shares of Common Stock. MedCap also owns warrants giving it the right to acquire (i) 6,000 shares of Series B-1 Preferred Stock for $60 per share (6,000 shares of Series B-1 Preferred Stock, in turn, would currently be convertible into 600,000 shares of Common Stock) and (ii) 100,111 shares of Series C Preferred Stock for $60 per share (100,111 shares of Series C Preferred Stock, in turn, would currently be convertible into 10,011,100 shares of Common Stock). CUSIP No. 225235209 SCHEDULE 13D Page 8 of 31 MMR as general partner and investment manager of MedCap and Toney as the sole managing member of MMR may be deemed to beneficially own the shares owned by MedCap in that they may be deemed to have the power to direct the voting or disposition of the shares. Neither the filing of this Schedule 13D nor any of its contents shall be deemed to constitute an admission that either MMR or Toney is, for any other purpose, the beneficial owner of any such securities to which this Schedule relates, and MMR and Toney disclaim beneficial ownership as to the Common Stock except to the extent of their respective pecuniary interests therein. Based on the number of shares outstanding reported in the Issuer's most recent annual report on Form 10-KSB and shares reported in filings with the SEC as being issued to various parties, the percentage of Common Stock beneficially owned by MedCap, MMR and Toney for the purposes of this Schedule 13D is 64.9%. (b) Reference is made hereby to Items 7 to 10 of pages 3, 4 and 5 of this Schedule, which Items are incorporated herein by reference. (c) On May 2, 2005, MedCap exercised a warrant that it held to acquire from the Issuer 22,187 shares of Series C Preferred Stock (currently convertible into 2,218,700 shares of Common Stock) for a total consideration of $1,331,220 (the Series C Preferred Stock acquired upon the exercise of the warrants are referred to as the "Warrant Shares"). The consideration for the Warrant Shares consisted of $1,331,220 in cash. Under the terms of the warrant, the exercise price was $60 for each share of Series C Preferred Stock. As part of a March 29, 2005 financing, the Issuer entered into a letter agreement with MedCap (the "Letter Agreement") pursuant to which the Issuer agreed to register for resale (i) all of the shares of Common Stock and the Common Stock that can be acquired upon the conversion of the Series C Preferred Stock that are held by MedCap and (ii) shares of Common Stock underlying all of the warrants that MedCap holds to acquire the Issuer's preferred stock; provided that, the Issuer is not required to register for resale Common Stock underlying the warrants unless such shares can be registered at the time that the shares of Common Stock listed in item (i) are registered for resale. Under a previous registration rights agreement executed by the Issuer, which in part is amended by the Letter Agreement, MedCap and certain other investors have a right to require the Issuer to register additional shares of Common Stock that may become outstanding following the exercise of certain warrants to acquire preferred stock and the conversion of such preferred stock into Common Stock; provided that, such shares of Common Stock have not already been registered for resale by the Issuer. CUSIP No. 225235209 SCHEDULE 13D Page 9 of 31 In connection with the exercise of the warrant, the Issuer and MedCap entered into an Amendment to Letter Agreement (the "Letter Agreement Amendment") which amended the date by which the Issuer is required to register for resale the securities held by MedCap and provided that the Common Stock into which the newly acquired Series C Preferred Stock can be converted also be registered for resale. Series C Preferred Stock is currently convertible at the option of its holder into 100 shares of Common Stock per share of Series C Preferred Stock. MedCap currently has outstanding warrants permitting it to acquire 100,111 shares of Series C Preferred Stock for $60 per share and the warrants for Series C Preferred Stock that MedCap holds would currently be indirectly convertible into 10,011,100 shares of Common Stock Under the terms of the warrants for the Series C Preferred Stock, the Issuer was required to make a distribution on the 22,187 shares of Series C Preferred Stock that were acquired by MedCap upon the exercise of the warrant at the same rate as the dividends previously paid on the outstanding shares of Series C Preferred Stock. As a result, upon the exercise of the warrant on May 2, 2005, MedCap received 110,935 shares of Common Stock (for no additional consideration) in addition to the 22,187 shares of Series C Preferred Stock. (d) Not applicable. (e) Not applicable. Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer MedCap is a party to an Amended and Restated Registration Rights Agreement entitling it to registration rights with respect to Common Stock issuable upon conversion of its shares of Series A Preferred Stock, Series B-1 Preferred Stock and Series C Preferred Stock, including any Series B-1 Preferred or Series C Preferred issued upon exercise of the Warrants. CUSIP No. 225235209 SCHEDULE 13D Page 10 of 31 MedCap and the Issuer are also parties to the Letter Agreement, as amended by the Letter Agreement Amendment, which amends in part the Amended and Restated Registration Rights Agreement. Under the Letter Agreement, the Issuer agrees to register for resale (i) all of the shares of Common Stock and the Common Stock that can be acquired upon the conversion of the Series C Preferred Stock that are held by MedCap and (ii) shares of Common Stock underlying all of the warrants that MedCap holds to acquire the Issuer's preferred stock; provided that, the Issuer is not required to register for resale Common Stock underlying the warrants unless such shares can be registered at the time that the shares of Common Stock listed in item (i) are registered for resale.

This certifies that, for value received, MedCap Partners L.P., together with its successors and assigns (the "Holder") is entitled to subscribe for and purchase, on the terms hereof, shares of Series C Preferred Stock (the "Stock") of Crdentia Corp., a Delaware corporation (the "Company"), which is convertible into shares of Common Stock of the Company (the "Common Stock"), subject to adjustment as provided herein. This Warrant is subject to the following terms and conditions: 1. Exercise of Warrant. The terms and conditions upon which this Warrant may be exercised, and the Stock covered hereby may be purchased, are as follows: 1.1 Term. Subject to the terms hereof, this Warrant may be exercised at any time after the date hereof, or from time to time, in whole or in part; provided, however, that in no event may this Warrant be exercised (the "Exercise Date") later than 5:00 p.m. (Pacific Time) on the earlier of (a) the close of business on October 18, 2009 or (b) the closing of a Corporate Transaction (as defined below) (the "Exercise Period"); provided that at least twenty (20) days prior to the occurrence of the closing of a Corporate Transaction, the Company shall have sent to the Holder notice of such event. CUSIP No. 225235209 SCHEDULE 13D Page 20 of 31 For purposes hereof, the term "Corporate Transaction" shall mean (a) the sale, conveyance or disposal of all or substantially all of the Company's property or business; (b) the Company's merger into or consolidation with any other corporation (other than a merger effected exclusively for the purpose of changing the domicile of the Company or a merger in which the owners of the voting stock of the Company prior to the merger own at least 50% of the voting interests in the surviving entity) or any other transaction or series of transactions, in which more than fifty percent (50%) of the voting power of the Company is disposed of (other than a sale by the Company of shares of its capital stock in an equity financing); or (c) the closing of an underwritten public offering of the Company's Common Stock pursuant to a registration statement under the Securities Act of 1933, as amended (the "Securities Act"), with aggregate net proceeds to the Company in excess of twenty-five million dollars ($25,000,000). 1.2 Number of Shares. This Warrant may be exercised for 799 shares of Stock, subject to adjustment as provided herein. 1.3 Exercise Price. The per share exercise price for the shares of Stock to be issued upon exercise of this Warrant shall be $60.00, subject to adjustment as provided herein (such price as adjusted from time to time as provided herein is called the "Exercise Price"). 1.4 Method of Exercise. The exercise of the purchase rights evidenced by this Warrant shall be effected by (a) the surrender of the Warrant, together with a duly executed copy of the form of a subscription attached hereto as Schedule 1, to the Company at its principal offices and (b) except as set forth in Section 1.5, the delivery of the aggregate Exercise Price by check or bank draft payable to the Company's order or by wire transfer to the Company's account for the number of shares for which the purchase rights hereunder are being exercised or any other form of consideration approved by the Company's Board of Directors (the "Board"). Each exercise of this Warrant shall be deemed to have been effected immediately prior to the close of business on the day on which this Warrant shall have been surrendered to the Company as provided herein or at such later date as may be specified in the executed form of subscription, and at such time the person or persons in whose name or names any certificate or certificates for shares of Stock shall be issuable upon such exercise as provided herein shall be deemed to have become the holder or holders of record thereof. CUSIP No. 225235209 SCHEDULE 13D Page 21 of 31 1.5 Net Issuance. (a) Right to Convert. In addition to and without limiting the rights of the Holder under the terms of this Warrant, the Holder shall have the right to convert this Warrant or any portion thereof (the "Conversion Right") into shares of Stock as provided in this Section 1.5 at any time or from time to time during the Exercise Period. Upon exercise of the Conversion Right with respect to a particular number of shares subject to the Warrant (the "Converted Warrant Shares"), the Company shall deliver to the Holder (without payment by the Holder of any exercise price or any cash or other consideration) that number of shares of fully paid and nonassessable Stock computed using the following formula: X = Y (A - B) A Where X = the number of shares of Stock to be delivered to the Holder Y = the number of Converted Warrant Shares A = the fair market value of the total number of shares of Common Stock into which one share of Stock can be converted on the Conversion Date (as defined below) B = the Exercise Price (as adjusted to the Conversion Date) The Conversion Right may only be exercised with respect to a whole number of shares subject to the Warrant. No fractional shares shall be issuable upon exercise of the Conversion Right, and if the number of shares to be issued determined in accordance with the foregoing formula is other than a whole number, the Company shall pay to the Holder an amount in cash equal to the fair market value of the resulting fractional share on the Conversion Date (as defined below). Shares issued pursuant to the Conversion Right shall be treated as if they were issued upon the exercise of the Warrant. CUSIP No. 225235209 SCHEDULE 13D Page 22 of 31 (b) Method of Exercise. The Conversion Right may be exercised by the Holder by the surrender of the Warrant at the principal office of the Company together with a notice in the form attached hereto as Schedule 2 specifying that the Holder thereby intends to exercise the Conversion Right and indicating the total number of shares under the Warrant that the Holder is exercising through the Conversion Right. Such conversion shall be effective upon receipt by the Company of the Warrant together with the aforesaid written statement, or on such later date as is specified therein (the "Conversion Date"). Certificates for the shares issuable upon exercise of the Conversion Right and, if applicable, a new warrant evidencing the balance of the shares remaining subject to the Warrant, shall be issued as of the Conversion Date and shall be delivered to the Holder promptly following the Conversion Date. (c) Determination of Fair Market Value.

In case the Company shall at any time subdivide its outstanding shares of Series C Preferred Stock into a greater number of shares, the Exercise Price in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, in case the outstanding shares of Series C Preferred Stock of the Company shall be combined into a smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased. 2.2 Dividends in Stock, Other Stock, Property, Reclassification. If at any time or from time to time the holders of the Series C Preferred Stock (or any shares of stock or other securities at the time receivable upon the exercise of this Warrant) shall have received or become entitled to receive, without payment therefor, (a) Series C Preferred Stock, or any shares of stock or other securities whether or not such securities are at any time directly or indirectly convertible into or exchangeable for Common Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution, or (b) any cash paid or payable otherwise than as a cash dividend, or (c) Series C Preferred Stock or other or additional stock or other securities or property (including cash) by way of spin off, split-up, reclassification, combination of shares or similar corporate rearrangement, (other than shares of Stock issued as a stock split, adjustments in respect of which shall be covered by the terms of Section 2.1 above), CUSIP No. 225235209 SCHEDULE 13D Page 24 of 31 Then and in each such case, the Holder hereof shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Stock receivable thereupon, and without payment of any additional consideration therefore, the amount of stock and other securities and property (including cash in the cases referred to in clauses (b) and (c) above) which such Holder would hold on the date of such exercise had he been the holder of record of such Stock as of the date on which holders of Series C Preferred Stock received or became entitled to receive such shares and/or all other additional stock and other securities and property. 2.3 Reclassification or Reorganization. If the Stock (or any shares of stock or other securities which may be) issuable upon the exercise of this Warrant shall be changed into the same or different number of shares of any class or classes of stock, whether by capital reorganization, reclassification or otherwise (other than a subdivision or combination of shares or stock dividend provided for in Section 2.1 above, or a Corporate Transaction, in which case this Warrant shall terminate if not exercised), then and in each such event the Holder shall be entitled to receive upon the exercise of this Warrant the kind and amount of shares of stock and other securities and property receivable upon such reorganization, reclassification or other change, to which a holder of the number of shares of Stock (or any shares of stock or other securities which may be) issuable upon the exercise of this Warrant would have received if this Warrant had been exercised immediately prior to such reorganization, reclassification or other change, all subject to further adjustment as provided herein. 2.4 Notice of Adjustments and Record Dates. The Company shall promptly notify the Holder in writing of each adjustment or readjustment of the exercise price hereunder and the number of shares of Stock (or any shares of stock or other securities which may be) issuable upon the exercise of this Warrant. Such notice shall state the adjustment or readjustment and show in reasonable detail the facts on which that adjustment or readjustment is based. In the event of any taking by the Company of a record of the holders of Common Stock for the purpose of determining the holders thereof who are entitled to receive any dividend or other distribution, the Company shall notify the Holder in writing of such record date at least twenty (20) days prior to the date specified therein.
