Howdy folks!

My name’s Jake, I’m a vertebrate palaeontologist based in Victoria, Australia.

My research is based on non-avian Theropoda from the ‘mid’-Cretaceous of Australia!

New article on Early Cretaceous flora of Victoria, Australia, with detailed plants in these formerly polar environments, including gorgeous artwork by @bobnichollsart.bsky.social. (P.S. Let me know when you see the theropod dinosaur tracks!) #FossilFriday 🧪🌿🪨

Scene of a cool temperate forest during the Early Cretaceous Period (125-105 million years ago) in what is now Victoria, Australia. In the foreground are many ferns and mosses in the understory and two large conifer trees on either side, framing a view in the background of a river and river floodplain with much woody debris. Further in the background is a green forest, which is in front  a mountain range with snow caps and an erupting volcano. Original artwork by Robert Nicholls.

G'day folks

I've got some online talks lined up this coming month for Australian heritage festival

I'll be speaking with Adele Pentland and Sally Hurst in three online talks - where we've dug, palaeontology questions, and why Australovenator is the best thing out of Australia since VB 😉

What's that sneaking up behind you? A new dinosaur discovery to be announced later today. Stay tuned...

So great to hear, congratulations to you too! Such an exciting group

Melissa found the bones too 😂 We'll have a whole animal in no time

Thanks Tony! Happy to give a similarly sized leg bone to your footprint :)

The Strzelecki unenlagiine also extends their range in Australia to at least ~10mil years.
These fossils all serve to improve our understanding of theropod diversity in Early Cretaceous Australia; we can now count noasaurids, carcharodontosaurs megaraptorids and unenlagiines.

Carcharodontosaurians being present in Australia is a big deal in itself.
Fossils from both the Eumeralla Formation and upper Strzelecki Group demonstrates that they were not only present in Cretaceous Australia, but that they were here for at least 10mil years.

Each specimen tells a compelling story.
The megaraptorid fossils hint at large-bodied forms at their earliest geological appearance, and are among the largest theropod fossils yet found in Australia.

Going back to Museums Victoria collections, I found one more theropod tibia of note, discovered in 2004. From the younger Eumeralla Formation, this specimen shares the unique morphology of Siamraptor, and the 1987 tibia — the intermalleolar notch.

Then in May of 2023, Melissa returned to the Eagles Nest locality (upper Strzelecki Group), and found yet another theropod tibia. Our analysis of this small but elongate specimen found it represented an unenlagiine, extending their record back to ~120Ma. 4/10

Later that year, fossil hunter Melissa Lowery found two new specimens from the upper Strzelecki Group at a new fossil locality. In two separate (but nearby) boulders were a large tibia, and two associated caudal vertebrae — both belonging to large-bodied megaraptorids.

In 2022, I came across a theropod tibia in the collections of Museums Victoria found in 1987! From the upper Strzelecki Group, this specimen had a unique feature — what we've termed the intermalleolar notch — seen only in Siamraptor, a carcharodontosaurian from Thailand.

They’ve only waited 120Ma.
A new glimpse into theropod diversity from Early Cretaceous Australia: megaraptorids, an unenlagiine, and for the first time, carcharodontosaurians.

AND HERE IT IS! It was really hard to not tell everyone because I knew for more than 2 years now. Please welcome Tameryraptor, a new name for Stromers carcharodontosaurid. Based on Stromers descriptions, drawings and newly found photographs the authors conclude...

Australovenator got lucky and is eating from the carcass of a large sauropod. It has burrowing into ribcage

New paper alert, just in time for #FossilFriday! A reevaluation of the #crocodylian fossils from the #Pliocene Otibanda Formation in Papua New Guinea. For a quick summary, check out the thread below 🧵👇

You can read the paper here (contact me if you need a PDF):

Figure 5 in the paper, showing one of the ziphodont teeth. Figure 9 in the paper, showing a map of Australia, New Guinea and surrounding islands. Known fossil localities that have yielded fossil remains of ziphodont crocodylians are indicated on the map.
