Some Triassic ‘Dinosaur Bones’ Belonged to Giant Ichthyosaurs, Paleontologists Argue
Oxytropidoceras posted a topic in Fossil News
Some Triassic ‘Dinosaur Bones’ Belonged to Giant Ichthyosaurs, Paleontologists Say SciNews, April 9, 2024 Perillo, M. and Sander, P.M., 2024. The dinosaurs that weren’t: osteohistology supports giant ichthyosaur affinity of enigmatic large bone segments from the European Rhaetian. PeerJ, 12, p.e17060. Yours, Paul H. -
Hi all Grateful for any ideas on this. Found at Aust cliffs, Westbury Bone Formation. Assumed to be a fish (poss reptile) jaw bone. My working assumption is it is either Gyrolepis albertii or Severnichthys acuminatus or one of the (six?) other bony fish taxa from this part of the world. Have quite a few other bits to ID soon too! I hope the images line up. The teeth get smaller as the rock, and bone, narrows, and line up where the rock has broken [due to falling from the cliff - not me!]. The appear to curve inwards. To me they look more Gyrolepis but I have never handled a jaw bone from the fish here so not too sure. Bone seems quite thick to me. Thank you, Ashley

These latest fossil images showcase the past six months of hunting and photographing tiny Triassic treasures from micro matrix derived from a 2 oz. (56 grams) chunk of bone bed from the Rhaetian Age of the Triassic Period at Aust Cliff, UK. They are approximately 200 million years old. I am fortunate to have been sent this very rich matrix from the UK by a friend and fellow avocational paleontologist across the pond who collected the matrix at Aust. After carefully breaking down about half of the densely packed bone bed rock, I found a wide variety of shark and boney fish fossils, most of which were entirely new to me. (As a result, I now have a large collection of papers regarding the Rhaetian Triassic!) Photographing the finds was very challenging due to the tiny size and the fact that they were very fragile and several broke with just a touch of the paintbrush hairs. These are some of the Triassic treasures that I found. (I will build a gallery for the entire collection.) Please let me know of any corrections needed. To begin, the shark teeth: Lissodus minimus is a common find, but difficult to recover complete. Rhomphaiodon minor is also quite common, and is much better preserved with complete roots. This was a nice surprise. The delicate Pseudodalatias barnstonesis lower is damaged, but identifiable. Duffinselache holwellensis I found it incredible that the tiniest fossils were some of the best preserved as were these Chondrichthyan dermal denticles. Here are some of the fish fossils collected. (I did my best at IDs for some of the teeth.) Thanks for looking
