Post-doc @narimanechatar.bsky.social is working with extinct sabertoothed cat-like carnivores from John Day, scanning a cast of Pogonodon platycopsis, housed in the UCMP. 3D scanning allows her to compare the shape and mechanical performances of its cranium and jaw. tinyurl.com/pogcranium

A similar analysis is in the works for sauropterygians; for now here is the paper: royalsocietypublishing.org/doi/10.1098/...
Predicting body length and assessing the shape of tail-propelled Mesozoic marine reptiles | Biology Letters
Body length is a crucial ecological predictor in vertebrates, yet total body length
proxies have seldom been assessed for ancient marine top predators. Here, we test
the strength of phylogenetic imput...

The good news is that isolated elements that are abundantly fossilised such as dorsal centra and propodials are good predictors of body size.
However, body size appears labile among subclades and genera, resulting in poor performance of phylogenetic imputation methods.
