Dortoka vremiri
Discussion
The species is named in honour of our late colleague Matyas Vremir, who passed away in June 2020, who skillfully prepared and studied the holotype specimen, and whose research greatly improved our understanding of fossil vertebrate faunas from Romania, including turtles.
Taxonomy
Dortoka vremiri was named by Augustin et al. (2021). Its type specimen is LPB (FGGUB) R.2297, a partial skeleton (a partial skeleton with most of the carapace and the complete plastron preserved in contact, together with the exposed in situ right scapula and right pubis), and it is a 3D body fossil. Its type locality is La Cărare, Sânpetru, which is in a Maastrichtian channel sandstone in the Sînpetru Formation of Romania.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| F. J. Augustin et al. 2021 | Medium-sized dortokid turtle characterized by the following unique combination of characters: (1) first pair of costals meet anterior to neural 1 and are sutured to one another near the midline; (2) last pair of costals meet posterior to neural 8 and have a well-developed median suture; neural 8 thus does not make contact with the suprapygal (also present in some specimens of D. vasconica); (3) cervical scale is absent (also seen in some specimens of D. vasconica); (4) first pair of pleural scales restricted to the first costals, not contacting the second costals (also present in D. botanica, an indeterminate dortokid from the Csehb anya Formation of Ihark ut, and an indeterminate dortokid from the Gosau Group of Muthmannsdorf, see below); (5) second pair of pleurals not contacting costals five (also present in D. botanica); (6) the sulcus between vertebrals 4 and 5 is located far posteriorly on the last neural and the last, fifth vertebral does not contact costals 7; (7) greatest width of entoplastron in the anterior third of the bone; (8) pectoral scales contacting the entoplastron (also present in D. botanica); (9) small extragulars, at least three times shorter than the gular (also present in D. vasconica and Eodortoka morellana). |
