Honestly, I’m glad that Anzu, Eoneophron, and Infernogallus weren’t found and named until the 2010s & 2020s. If they were found and named during the 90s or earlier, they would’ve been collapsed into a growth series of Anzu by the 2000s.

This young Albertosaurus would've been able to find food well on its own and shifted diet/niche with age. In this respect, I guess you could say it was more like say, Epomis larvae, baby crocodilians, or predatory tadpoles than baby mammals. #FossilFriday

Every time I delve into a paper co-authored by Barnum Brown, especially those from the last half of his career, I'm impressed by how forward-thinking he was. I think Brown's contributions to the intellectual growth of paleontology--esp. vertebrate paleo--are often underestimated.

I obviously can’t say for sure if that’s the case or not, but the high mix of tyrannosaurine & albertosaurine characters certainly makes it reasonable imo. (7/7)

Milo Gaillard @milogaillard2.bsky.social · 02/10/2026
This mosaic is so great that it makes me wonder something. Although Tromerosaurus is clearly NOT the common ancestor of all of Tyrannosauridae, I wonder if said common ancestor strongly resembled Tromerosaurus. (6/7)

Milo Gaillard @milogaillard2.bsky.social · 02/10/2026
In fact, it’s named Tromerosaurus (“terrible or frightful lizard”), because of it’s mosaic of characters between Gorgosaurus (“dreadful or terrible lizard”) and Daspletosaurus (“frightful lizard”). It’s basically defined by being a tyrannosaurid character blender. (5/7)

Milo Gaillard @milogaillard2.bsky.social · 02/10/2026
In fact, Tromerosaurus blurs the line between Tyrannosaurinae & Albertosaurinae so much that even in this paper arguing that it’s an albertosaurine, it goes back and forth between the two subfamilies. Albertosaurine in 3 of the 5 trees, tyrannosaurine in the other 2. (4/7)

Milo Gaillard @milogaillard2.bsky.social · 02/10/2026
Aside from having diagnostic traits of its own, it also shares traits seen in Albertosaurus & Gorgosaurus, but differs from them in traits which it shares with Daspletosaurus, while also differing from that in traits resembling those of Teratophoneus, etc. (3/7)

Milo Gaillard @milogaillard2.bsky.social · 02/10/2026
Specimens of this new taxon were originally thought to belong to either Gorgosaurus or Daspletosaurus, and there’s a reason for that. Tromerosaurus has a mosaic of both tyrannosaurine & albertosaurine characters, and blurs the line between the two subfamilies. (2/7)

Milo Gaillard @milogaillard2.bsky.social · 02/10/2026
#FossilFriday I was aware that this research was coming, but I didn’t expect it to be published already. Tromerosaurus solumons is the first time we have an albertosaurine genus that is not Albertosaurus or Gorgosaurus! Or at least probably an albertosaurine (1/7)

I submitted my letter of support for the Sternberg Museum to the Kansas Board of Regents. Let's hope it helps
TEXT: Closing the Sternberg Museum of Natural History
Dear Kansas Board of Regents,
My name is Anthony Maltese, a former Kansas resident from 1990-2004, University of Kansas
graduate, and professional paleontologist specializing in the sea life of ancient Kansas. It has been
recently disclosed that Fort Hays State University intends to close the Sternberg Museum of Natural
History, with likely serious consequences to both its staff and collections. I cannot think of a more
disastrous and short-sighted response to a budget shortfall. Over the past three decades of my
career, I have worked closely with the Sternberg Museum excavating fossils with staff, using the
museum for research, leading field trips for students and professionals, and making replicas of
specimens that educate museum visitors worldwide. The collections housed at the museum are an
irreplaceable record of the history, both modern and ancient, of Kansas and are unique in that they
are housed in the area where they were excavated from.
The collections are so important that I have helped donate many scientifically significant specimens to
the museum, understanding this places them in the public trust for perpetuity. Budget decisions are
difficult; however, the destruction of this extremely valuable institution is not a reasonable solution.
While I no longer reside in Kansas, I think about the Sternberg Museum on a nearly daily basis and
use its holdings to advance our understanding of what came before us. Destroying this vast resource
is absolutely the wrong thing to do to address these problems. Keep the Sternberg Museum.
