Geologists at Lund College in Sweden have mapped 300 years of analysis on the prehistoric marine reptiles referred to as ichthyosaurs. Utilizing a uniquely well-preserved fossil, the crew has additionally created the scientifically most modern reconstruction of an ichthyosaur at the moment obtainable.
Fish lizards, or ichthyosaurs, have been a really profitable group of animals that, very like immediately’s whales, migrated from land to the oceans the place they thrived for about 160 million years. These dolphin-like reptiles lived from the Early Triassic to the Late Cretaceous, about the identical time as dinosaurs dominated the Earth.
The fish lizards, who sustained themselves on a weight-reduction plan of turtles and octopuses, amongst different issues, have left behind a wealthy fossil file. This consists principally of bones and enamel, however just lately the invention of sentimental tissues — equivalent to pores and skin, muscle tissues, fats, and pigment — has opened up new alternatives for understanding the biology and ecology of those animals.
In a brand new research revealed in Earth-Science Evaluations, a gaggle of geologists at Lund College has analyzed present fish lizard analysis – one thing that can profit future paleontologists.

“This analysis historical past spans 300 years. It's price noting that the time period ichthyosaur was coined in 1814, i.e. virtually 30 years earlier than the time period dinosaur,” says Mats E. Eriksson, professor of paleontology at Lund College.
Based mostly on the world’s collective information of those primordial animals, in addition to laborious and tender fossil elements, the researchers enlisted the assistance of the Danish sculpture firm 10 Tons, to create a scientifically right life-size reconstruction.
“Our reference level was a fish lizard that was present in Holzmaden, Germany. This fossil has beforehand been the topic of an in depth research on the biology and coloration of fish lizards, which I did along with Mats and a number of other different colleagues, and was revealed in Nature,” explains Johan Lindgren, geology researcher at Lund College.
Quite a lot of strategies, together with clay sculpturing and 3D printing, have been used within the work, one thing that took simply over a 12 months. The sculpture initiative, which could possibly be carried out with assist from the Crafoord Basis, goals to mirror the present state of analysis. The sculpture is now on public show on the Division of Geology in Lund.
“Our reconstruction is the scientifically most trendy, and hopefully right, interpretation of what these animals regarded like. It is going to be useful for college kids and researchers who need to be taught extra concerning the iconic fish lizard,” concludes Mats E. Eriksson.
