At https://phys.org/news/2026-02-ancient-seafloor-arkansas-sharkansas-shark.html … we have a shark graveyard in Arkansas – going back 325 million years ago on the geological column. As far as fossils are concerned, sharks are rare. There are numerous examples of sharks teeth in washed sediments and so many they are even sold in packs to schoolboys. They are found in geological formations over many a long year – including fairly recent sediments. Sharks go back a long way. However, sharks in 3 dimensions are preserved in the Fayetteville Shale deposit. Shale is basically ancient mud. There had to be a lot of mud to preserve a whole shark carcass – but at Fayetteville there are a lot of sharks. We are told they are preserved as a result of low oxygen levels and a highly acidic environment – presumably having dropped to the sea floor. Catastrophism might suggest otherwise.

At https://dailygalaxy.com/2026/02/cave-sealed-reveals-16-ancient-fossils/ … fossils found in a cave in New Zealand have been preserved intact, and untouched for at least a million years. They capture a forest eco-system – and animals unknown to science. It includes 12 bird species and 4 different frogs. Birds trapped in a cave. Well, New Zealand is famous for its flightless birds – so yes, possible. The fossils were found between two layers of volcanic ash – each tied to a different eruption. Volcanic catastrophism.
