Ancient ammonoids' shell designs may have aided buoyancy control

Researchers previously focused on the roles of these complex structures in resisting pressure on the shell, but University of Utah researchers provide evidence for a different hypothesis. Complex sutures, they found, retained more liquid through surface tension, possibly helping the ammonoids fine-tune their buoyancy. ....

Over the past few years, Naturalis has painstakingly made 3D scans of every single bone in Trix the T.rex s skeleton. Based on these scans, a modeler made a three dimensional design and reconstructed the bones that were missing. This design was printed in 2020, a 12.5 meter (41 feet) replica weighing about 300 kgs (660 lbs). Employees of Naturalis and the Leiden School for Instrument Makers (LIS) then assembled the prints into a kit that is easier to assemble. This way, the Dinosaur Museum in Nagasaki will not receive hundreds of separate prints, but only 50 larger parts. ....

Paleontologists in Patagonia have unearthed a new theropod with keen hearing


As detailed in a new research paper published last week in the Journal of Vertebrate Paleontology, the coarse-looking beast grew to roughly 16.4 feet in length, sported long claws, delivered a vicious bite courtesy of razor-sharp teeth, and possessed a powerful sense of smell.
Its most distinguishing ability points to an acute sense of hearing, possibly far greater than the majority of prehistoric beasts of the time. Its large blunt skull was formed by thick bones, bulges, horns, and sharp ridges, similar in many ways to today s reptiles like the Gila Monster or iguanas.
