Paleontologists from the Institute of Paleobiology of the Polish Academy of Sciences and the Institute of Evolutionary Biology at the University of Warsaw invite adults, primarily students of biology and geology, to participate in paleontological excavations. In July and August, we will be searching for vertebrate fossils in Triassic sediments.

The camps are free of charge. Accommodation and meals are provided.

Space is limited. Applications with a cover letter, contact information, and date preferences should be submitted by May 31st using the online form:
https://forms.gle/C7HikmxVnoqNGLrdA

Dates (specific camp locations will be announced later):
Camp I (July 5th - 18th)
Camp II (July 19th - August 1st)
Camp III (August 2nd - 15th)
Camp IV (August 16th - 29th)


Paleontolodzy z Instytutu Paleobiologii PAN i Instytutu Biologii Ewolucyjnej Uniwersytetu Warszawskiego zapraszają osoby pełnoletnie, przede wszystkim studentów kierunków biologicznych i geologicznych, do udziału w wykopaliskach paleontologicznych. W lipcu i sierpniu będziemy poszukiwać skamieniałości kręgowców w osadach triasowych.

Obozy są bezpłatne. Zapewniamy nocleg i wyżywienie.

Liczba miejsc jest ograniczona. Zgłoszenia z listem motywacyjnym, danymi kontaktowymi i preferencjami terminowymi należy przesyłać do 31 maja przez formularz online:

Terrible news that Hans-Dieter Sues has died. Way too young.
Hans (on the right) & Sasha Averianov (left) invited me to study Timurlengia with them. I'll always appreciate it.
Hans was eminent, always nice and cheerful to me, a man of ethics and faith. RIP.

A shake-up of the dinosaur family tree! Rhabdodontids are not ornithopods. They are ceratopsians.

There were horned dinosaurs in Europe! As shown by a new fossil of Ajkaceratops from Hungary!

Volume renderings of CT scan data of the holotype skull of Nanotyrannus lancensis (CMNH 7541). The top image is mostly a left lateral view. The bottom image is a ventral view showing the caudal half of the hyoid bone preserved in place.

Volume renderings of CT scan data of the holotype skull of Nanotyrannus lancensis (CMNH 7541). The top image is mostly a left lateral view. The bottom image is a ventral view showing the caudal half of the hyoid bone preserved in place.

Additional images (all in ventral view) of the holotype skull of Nanotyrannus lancensis (CMNH 7541). The top right image is from the original 1946 article by Charles Gilmore showing the full ceratobranchial hyoid bone in place. The bottom photograph (that I snapped in 2005 when I had the skull on loan for study & CT scanning) shows the caudal half of the hyoid bone preserved in place. The top left image is similar to the bottom image but is grayscale except for the hyoid bone.

The main photograph (again, that I snapped in 2005 when I had the skull on loan for study & CT scanning) shows the caudal half of the hyoid bone of Nanotyrannus (CMNH 7541) preserved in place, but it's more of a front view. Notice the broken end of the ceratobranchial in a close-up in the inset.

#FossilFriday The awesome new article in Science by
@griffinlabpaleo.bsky.social et al. adds more evidence for the validity of Nanotyrannus by showing that the hyoid bone in the holotype has adult bone histology. Here are some more images showing the ceratobranchial bone in place in the skull. 🦖
