Rostral and body shape analyses reveal cryptic diversity of Late #Jurassic #batomorphs (#Chondrichthyes, #Elasmobranchii) from Europe: Julia Türtscher et al. https://onlinelibrary.wiley.com/doi/10.1002/spp2.1552

"They examined 52 #fossil rays from the #LateJurassic period. These rays are 150 million years old, from a time when Europe was largely covered by the sea, except for a few islands, comparable to today's Caribbean."

Rays were more diverse 150 million years ago than previously thought

In a new study published in the journal Papers in Palaeontology, an international team of scientists led by paleobiologist Julia Türtscher from the University of Vienna has explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity—including a new ray species. This study significantly expands the understanding of these ancient cartilaginous fish and provides further insights into a past marine ecosystem.
