A few years ago, I started my personal project on the Upper Cretaceous Northumberland Formation of British Columbia, and I know proper background has been a long time coming. So here's a blogpost explaining what it's about, how and why I started it, and my future plans Link in reply ⬇️

Saw a Siler cupreus male(?) in Japan yesterday! It was raising its front legs and shaking its abdomen, so I assumed it was doing a display at the ants at first, but this myrmectophagous species may have been trying to hunt them instead

An albino Jormungandr circles a Ginko adiantoides sapling that was blown into the sea by a recent thunderstorm. Jormungandr is a recently described genus of mosasaur from the Pierre Shale Fm. described by Zietlow et al., (2023) congrats on the successful publication!

An albino Jormungandr circles a Ginko adiantoides sapling that was blown into the sea by a recent thunderstorm.

It's biting its tail in reference to its namesake, Jõrmungandr the Midgard Serpent, with the ginkgo sapling being a reference to Yggdrasil, the World Tree.

On its snout, the scars spell out "ᛃᛟᚱᛗᚢᚾᚷᚨᚾᛞᚱ" which is Jörmungandr in Old Futhark.

While it may look like a squid, Enchoteuthis is more at home in #OCTOtober, as its closest living relatives are octopuses While most common in the Late Cretaceous Western Interior Seaway, this specimen shows that the genus also lived in the Pacific, and it has even been found in Australia! #SciArt 🐡

Australosuchus, the southern crocodile was the latest mekosuchine I looked into A medium sized crocodilians around 3 meters long and with a unique skull, it is the only crocodilian from the Oligocene and Miocene Lake Eyre Basin This is peculiar, as the north shows that crocs were diverse at the time

a comparisson between Australosuchus clarkae and Steve Irwin, Australosuchus was around 3 meters long, a map shows the localities where it was found in South Australia

A skull reconstruction of Australosuchus, highlighting the peculiar anatomy of this form. it generally resembles a crocodilian, but instead of notches the 4th tooth of the lower jaw slid into almost fully enclosed pits
