In this episode of Epoch News, we cover a new Pterosaur, Jurassic amber, new dinosaurs, and more!

In this episode of Epoch News, we cover new Abelisauroids, Dicynodont sexual dimorphism, marine reptile geographic regions, and more! 

In this episode, we cover most of the biggest publications released in the past month, as we've now decided to cover the newest discoveries monthly!

In this episode, we cover a brand new species for the king of all dinosaurs, Tyrannosaurus! Named Tyrannosaurus mcraeensis, the new species has enough diagnostic traits to not only differ from T. rex, but the rock layer the fossils were found expands the time range for the genus overall, showing that Tyrannosaurus actually first appeared 72.7 million years ago, rather than 68 million years ago as previously suggested.

In this episode, we cover two new taxa: A new early Cambrian worm from Greenland, and a new Rebbachisaurid Sauropod from Argentina!

Timorebestia is a new genus of stem-Chaetognath (primitive arrow worm) from the Sirius Passet Biota, located in Greenland. What makes Timorebestia a special find is its overall gigantic size compared to modern arrow worms, suggesting that primitive groups like these played a higher ecological role in the Cambrian Explosion.

Sidersaura is a new genus of Rebbachisaurid Suropod from the Late Cretaceous rocks of the Huincul Formation, located in Argentina. What makes Sidersaura a special find is that it's so far the latest Rebbachisaurid to ever be discovered, showing that Rebbachisaurids, if not Diplodocoids as a whole, went extinct deeper into the Late Cretaceous than previously thought.

In this episode, we discuss a brand new genus and species of Polycotylid from the Late Cretaceous Sharon Springs Formation, known from two specimens discovered in Wyoming and South Dakota. Unktaheela specta is unique for not only being the smallest Polycotylid ever found, but its also unique for the flat processes over its eyes and for its binocular vision.

In addition, two species from the genus Dolichonrhynchops, were redescribed as new genera, named Martinectes bonneri (D. bonneri) from the Sharon Springs Formation in Wyoming, and Scalamagnus tropicensis (D. tropicensis) from the Tropic Shale in Utah.

Lastly, with the description of all three genera, a new clade of Polycotylids has been erected, named Dolichorhynchia, made for any genus closely related to Dolichorhynchops.

In our first ever episode, we cover an older publication made in 2021, describing two brand new Baryonychine Spinosaurids from the Wessex Formation, located in the Isle of Wight, England.

Named Ceratosuchops inferodios and Riparovenator milneri, both Spinosaurs have enough diagnostic material to be considered as different genera thanks to both animals being known from partial braincases.

What makes both genera special is that their time range indicates a European origin for Spinosauridae. In addition, anatomical traits reveal that they are phylogenetically related to the African Suchomimus, creating the first ever Spinosaurid subgroup within Baryonychinae, aptly named Ceratosuchopsini.
