Hi, This summer I collected a handful of microfossils from outcrops of the late cretaceous Frenchman formation in southern Saskatchewan. The Frenchman is stratigraphically equivalent to and geographically near the Hell Creek formation, and both represent a more or less equivalent terrestrial environment and time period - that is, a terminal cretaceous swampy river delta. Crocodilians were definitely the most abundant among my finds, as well as plant fossils and nondescript dinosaurian bone fragments, but I'd like to share a few oddballs, as well as a tooth, for identification. First is this thing - it's certainly a piece of a skull, but it's a little too small for me to determine if it's fossilized or not. It could very well be from a modern animal. It may be difficult to make out in the photo, but the side without the tiny holes in it actually has some skull suture lines on its surface, Secondly is this piece, which appears to be a scute of some kind. While I encountered many crocodilian scutes on this trip, this one stood out because of its small size and completeness. I don't have a photo, but the person I was collecting with found a similar one that had what looked like enamel on the smooth side, Finally is this tooth. It's the only tooth we found, and it seems to be from a crocodilian, but I'd like a confirmation and possibly more information if possible, Side view: Lingual view: Facial view: Root: Thanks for your attention. Here's some bonus photos from the trip of a metasequoia pinecone and the K-Pg boundary as seen in the field,
Step aside Sue, the T rex. The attached article finally describes the largest T rex discovered from the Frenchmans Formation of Saskatchewan, Canada after being discovered in 1991 Abstract Here we describe an extremely large and relatively complete (roughly 65%) skeleton of Tyrannosaurus rex (RSM P2523.8). Multiple measurements (including those of the skull, hip, and limbs) show that RSM P2523.8 was a robust individual with an estimated body mass exceeding all other known T. rex specimens and representatives of all other gigantic terrestrial theropods (Paywalled) https://onlinelibrary.wiley.com/doi/10.1002/ar.24118#.XJQsTuqqy7k.twitter An Older and Exceptionally Large Adult Specimen of Tyrannosaurus rex W.
