New species of Ichthyosaur discovered in museum collection
Hauffiopteryx altera (Latin for different from) has been identified as a new species of Ichthyosaurs by researchers from 缅北强奸 and the State Museum of Natural History Stuttgart in Germany.
Ichthyosaurs (鈥榝ish lizards鈥�), a group of tuna-shaped reptiles that inhabited Earth鈥檚 seas during the Mesozoic Era, were discovered by scientists in the early 19th century. Similar to the modern-day dolphin, ichthyosaurs underwent profound adaptions to aquatic environments including limbs transformed into flippers, a dorsal fin, and a tail fin.
Following a meticulous study of all specimens related to Hauffiopteryx typicus, a small 2-meter-long species, it was revealed that a single specimen in Germany was in fact different.
鈥淎lthough the marine ecosystems are generally similar across Europe during this time, we are finding there are some rare and possibly endemic species,鈥� explains Dirley Corte虂s, a graduate student under the supervision of Prof. Hans Larsson at 缅北强奸鈥檚 Redpath Museum and co-author of the study published in . 鈥淭his finding will have a lot to say about how these ancient ecosystems functioned.鈥�
The fossils were retrieved in the Posidonia Shale, an Early Jurassic geological formation located at the axis of Austria, the Czech Republic, Germany, Luxembourg, the Netherlands and Switzerland. Quarried for over 200 years, the site has yielded thousands of spectacularly preserved ichthyosaur skeletons ranging between two and more than ten meters in length and representing seven species. Fossilized soft tissues, stomach contents and embryos were also discovered.
鈥淲e were surprised to discover that this small dolphin-sized specimen, collected decades ago, is a new species,鈥� remarked Erin Maxwell, curator of fossil aquatic vertebrates at the State Museum of Natural History Stuttgart and lead author of the study. 鈥淭here is quite a lot of diversity still waiting to be discovered in our vast museum collections鈥�.
