A study of exceptionally preserved fossils led by a graduate student at The University of Texas at Austin has found that rising global temperatures and a rapidly changing climate 183 million years ago may have created fossilization conditions in the world’s oceans that helped preserve the soft and delicate bodies of deceased marine animals.
A study of exceptionally preserved fossils led by a graduate student at The University of Texas at Austin has found that rising global temperatures and a rapidly changing climate 183 million years ago may have created fossilization conditions in the world’s oceans that helped preserve the soft and delicate bodies of deceased marine animals.
The fossils include squid-like vampyropods with ink sacs, ornate crustacean claws and fish with intact gills and eye tissue.
Despite being from different locations and marine environments, the fossils were all preserved in a similar manner. Geochemical analysis revealed that the conditions needed to preserve such captivating fossils could be connected to Earth’s climate.
“When I started the research, I had no idea if they would preserve the same way or a different way,” said lead author Sinjini Sinha, a graduate student at the UT Jackson School of Geosciences. “I was curious what led to the exceptional preservation.”
