Did Allosaurus survive up to the earliest Cretaceous
Joseph Fossil posted a topic in Questions & Answers
The Theropod Dinosaurs of the genus Allosaurus since their discovery in 1877 are perhaps one the most recognizable theropods of the whole Jurassic period (201.4 ± 0.2-145.0 Million Years ago) despite emerging only in the late Kimmeridgian stage of the Jurassic period. Growing up to 9.7 meters (32 feet) in length fully grown, Allosaurus (also known as the Lions of Jurassic) were the apex predators of most of the terrestrial ecosystems they inhabited. The only theropods from these time that were higher in the food chain were some European non-Allosauroid Theropods and other members of Allosauroidea including the much rarer Epanterias (validity debated, possibly grew fully grown up to 12 meters (40 feet) in length) and Saurophaganax (validity confirmed, fully grown reached 10.5 meters (34 feet) in length).

By artist Frederic Wierum Image Source: https://fredthedinosaurman.artstation.com/projects/Qg0WB The Allosauroids eventually gave rise to some of the largest theropod dinosaurs known in the fossil record currently including the closely related South American genus Giganotosaurus from the Cenomanian stage of the Late Cretaceous period (99.6-95 Million Years ago) in what is now Argentina (which fully grown grew up to 12-13 meters (39-43 feet) in length). But Allosaurus itself has largely been considered to have lived only in the latest stages in Jurassic period (155-145 Million Years ago). I have found some records that might challenge this assumption!!! Digital Reconstruction of an adult Allosaurus sp.

Hi all, I was recently told about supposed Aigialosaurus/aigialosaurid (mosasaurus) material from the Wealden at Bexhill-on-Sea in East Sussex, and was wondering whether anybody knows anything more about this. Because, as far as I'm aware (Wikipedia), Aigialosaurus is described from Hvar in Croatia and, moreover, temporarily restricted to the Cenomanian, whereas these remains, stemming from the Wealden, would be Early Cretaceous in age (Berriasian through Aptian) - most likely Valanginian, as they were recovered from Bexhill-on-Sea. (Image source) I must say these remains do look rather mosasauroid, although I've been unsuccessful in finding further information on the specimen, which is supposed to be housed in the Bexhill Museum. The person who first told me about them remembers having seen a newspaper article, believes the British Natural History Museum was involved with the specimen back then, and had heard about a paper being written about it. That's about all I have to go on for now. So my questions right now are: does anyone have more information on this specimen; know of the publication; and what do people here generally make of this piece: is it mosasauroid, or could it be something else? @paulgdls @DE&i @Praefectus @caterpillar @The Amateur Paleontologist @Kosmoceras @ThePhysicist @Welsh Wizard @DanJeavs

I have some teeth from Cognac area to ID. Selachians found are Parvodus, Polyacrodus, Lissodus, Hybodus, Hybodontidae, Rhinobatidae but I don't know them. Is someone knows this fauna ? Here are 4 pics done with my phone, but perhaps I have to try with an APN... They are very very small. It is written "Portlandian" on the pics but the right stage is Berriasian. I think I have 2 different species in my collection, and I must do a lot of pics Thanks for you help. Coco

I have been looking for an Atrociraptor marshalli tooth for quite awhile. I happened to find someone who had one and he was nice enough to sell it to me, along with a French dromaeosaurid tooth. I got them both in the mail today. Thank you to the seller, who’s a TFF member!
