Hi all! I'm Jorgo, a palaeontologist that studies the evolution, anatomy, and taxonomic diversity of crocodylomorphs (i.e., crocodylians and their extinct relatives).

The ziphodont teeth were the main focus of our study. #Ziphodonty is a type of dentition that is characterized by labiolingually compressed tooth crowns (i.e., longer than wide tooth crowns) that have serrated carinae (i.e., serrated front and back cutting edges).

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.

Hello Bluesky! My name is Jorgo Ristevski, and I am a paleontologist that studies crocodylomorphs.
Although my research has been primarily focused on extinct crocodylians, I have also published on extant ones. In my book chapter in the Encyclopedia of Animal Cognition and Behavior, I covered the basic basics of anatomy in living crocodylians: https://link.springer.com/referenceworkentry/10.1007/978-3-319-55065-7_955. Contact me if you need a PDF copy of the chapter. Me holding the holotype specimen of the mekosuchine crocodylian Trilophosuchus rackhami. Both of my papers on this croc are Open Access, and you can read them over at The Anatomical Record (https://anatomypubs.onlinelibrary.wiley.com/doi/10.1002/ar.25050) and Journal of Anatomy (https://onlinelibrary.wiley.com/doi/10.1111/joa.13732). This image is from my paper published at Alcheringa, where the evolutionary history of crocodyliforms in Australasia was reviewed in detail. The paper is Open Access and you can read it here: https://www.tandfonline.com/doi/full/10.1080/03115518.2023.2201319 This image is from my paper published at the Journal of Anatomy, where I described the paleoneurology of the mekosuchine crocodylian Trilophosuchus rackhami.
