: The newly discovered species, complete fossils are only known from Germany. This species is also the largest species of all and can grow up to 170 cm in size. Credit: Türtscher et al. Papers in Palaeontology,has explored the puzzling world of rays that lived 150 million years ago and discovered a previously hidden diversity – including a new rayThis study significantly expands the understanding of these ancient cartilaginous fish and provides further insights into a past marine ecosystem.
As only the teeth of fossilized rays are usually preserved, such rare skeletal finds provide exciting insights into the early evolution of this group. Although the exceptionally well-preserved fossils have been known for some time, they have been largely unexplored. Türtscher’s study is the first comprehensive analysis of the variation in body shape in these rays.
The results show a greater diversity of holomorphic rays in the Late Jurassic than previously thought. “Until now, only three holomorphic ray species have been confirmed from the Late Jurassic, but thanks to this study, a total of five species have now been identified,” says Türtscher.
