The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

The Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.

Determination of snake-necked turtle Hydromedusa tectifera (Cope, 1870) (Testudines: Chelidae) plasma protein concentrations by refractometry and the biuret method

Comparative Clinical Pathology, 2010
The purpose of this study was to evaluate the accuracy of hand-held refractometer in determining plasma protein concentrations in South American snake-necked turtle (Hydromedusa tectifera) as compared with the standard biuret method. The results indicated that plasma protein values may be accurately determined in snake-necked turtle with a hand-held ...
