New Application of Histological Staining for Visualization of Endogenous Proteins in Fossil Material Biochemical applications are increasingly utilized in paleontological studies, especially for detecting ancient proteins in fossil samples. Histopathological staining techniques have been applied, but...

New paper: new application of histological staining for visualization of endogenous proteins in fossil material. We can stain fossil tissue and see collagen in situ! pubs.acs.org/doi/10.1021/...

CT scan of the head clasper (tenaculum) from the Spotted Ratfish (Hydrolagus colliei), compete with its rows of shark-like teeth!

Our paper features fossil reconstruction art (of Helodus simplex) by Ray Troll - https://www.trollart.com/

New Pre-Print Alert! "Teeth Outside the Jaw: Evolution and Development of the Toothed Head Clasper in Chimaeras." We use fossil evidence, development and CT scans through ghost shark ontogeny to describe the emergence of the tenaculum! 👻🦈🦷 @karlycohen.bsky.social

Bone labeling experiments and intraskeletal growth patterns in captive leopard geckos (Eublepharis macularius) In this study, we used fluorochrome labels in captive leopard geckos (Eublepharis macularius) to track bone growth and intraskeletal variability from embryonic to adult growth stages. Overall, the ti...

New paper alert! This was a fun study examining intraskeletal growth patterns in leopard geckos using fluorescent labeling. Labels administered in ovo are still present up to 4 years post-hatching! doi.org/10.1111/joa....
