2014 journal article

A Pelomedusoid Turtle from the Paleocene-Eocene of Colombia Exhibiting Preservation of Blood Vessels and Osteocytes

JOURNAL OF HERPETOLOGY, 48(4), 461–465.

By: E. Cadena n & M. Schweitzer n 

topics (OpenAlex): Paleontology and Evolutionary Biology; Evolution and Paleontology Studies; Turtle Biology and Conservation
TL;DR: The potential organic preservation of osteocytes and blood vessels for this specimen is demonstrated, indicating that preservation of soft tissue such as vessels and bone cells in the fossil record is independent of bone type, fossil site, or locality; and that it is even possible to occur in tropical depositional environments during a period of maximum global warming such as the Paleocene–Eocene.

2012 review

Variation in osteocytes morphology vs bone type in turtle shell and their exceptional preservation from the Jurassic to the present

[Review of ]. BONE, 51(3), 614–620.

By: E. Cadena n & M. Schweitzer* 

author keywords: Osteocyte morphology; Testudines; Cenozoic; Mesozoic; Exceptional preservation
MeSH headings : Animal Shells / anatomy & histology; Animal Shells / cytology; Animals; Biological Evolution; Bone Demineralization Technique; Bone and Bones / anatomy & histology; Bone and Bones / cytology; Cell Separation; Cell Shape; Extinction, Biological; Fossils; Osteocytes / cytology; Preservation, Biological; Time Factors; Turtles / anatomy & histology
topics (OpenAlex): Paleontology and Evolutionary Biology; Evolution and Paleontology Studies; Ichthyology and Marine Biology
TL;DR: It is demonstrated that the morphology of osteocytes in each of the three bone layers is conserved through ontogeny, and that these morphological variations are phylogenetically independent, as well as independent of the bone origin (intramembranous or endochondral). (via Semantic Scholar)
