Always nice to wake up to a new bite mark paper in my inbox, AND it's a large-scale survey to get at patterns of behavior. 🧪

Day 4 of #dinovember! This is Brachylophosaurus, the hadrosaurid from late Cretaceous North America! It's claim to fame was it was a "mummy" fossil; having a bunch of skin impressions preserved along with the skeleton. #Dinovember2026 #CapsDinos #Paleoart
The large hadrosaurid Brachylophosaurus from the late Cretaceous. It has a large nasal build on it's face, "mitten" like front feet and small spine-like growths running down it's back. It has light brown skin with a pale cream underbelly that strips out down along it's tail. The top of it's head is a rusty orange with a lighter color orange running down it's back. The ends of its limbs also have a gradient of orange with dark claws on it's back limbs. It's walking towards the viewer with it's golden eye looking off to the side.

There are these repeated injuries in hadrosaur tails. There were a few theories on this, but one of them stands out. No easy way to say this: some dinosaurs were really into rough sex. 🧪

Let's pretend this is just paleoartistic restoration of hadrosaurid mating postures. The different diagrams show the mating postures of two generic hadrosaurids that have been hypothesized in recent years in academia and in the media (A–E). Because we do not have any fossilized reproductive organs, we cannot define a specific mating position. Artworks by the paleoartist Troco.

Today's dino is Gongshuilong, the Hadrosaurid dinosaur from the late Cretaceous in what is now China. Their unique feature is the elongated neural spines along it's tail that gave it a bit of a sail-like structure. #CapsDinos #Paleoart #Dinosaur
Gongshuilong, the hadrosaurid dinosaur. It has a long head with a beaked mouth. It has a large, robust body. It's forelimbs are hoove-like and was able to walk both on all fours and on it's hind legs. It's long tail has a sail-like extension along the top. It has dark blue skin with large splotchy white patterning along it's tail and lower back. Along it's lower hind legs and upper back and forelimbs is a darker black. It has small osteoderms running down it's back, from it's head to the tip of it's tail.

- 2 tons in mass! This makes it slightly smaller than the closely related Daspletosaurus, but still plenty big enough that the largest local herbivores, the hadrosaurid Probrachylophosaurus and the ceratopsid Xenoceratops, would be wise to keep their guard up around it! (2/2)

PUMPED to be giving the tooth anatomy lecture today for the course I'm TAing! 🦷✨ hope these students are ready for some wild teeth in vert evolution, inc Helicoprion (ancient shark w tooth whorl!), Dorudon (basilosaurid whale w cuspy postcanines), and Edmontosaurus (hadrosaurid w dental battery)!
This illustration of Helicoprion, created by artist Ray Troll in 2012, depicts the head of a shark on the left side of the image, displaying a tooth whorl. The shark's head is dark grey at the top, fading to slate grey at the bottom, and the teeth are black. The eye of the shark is amber, and several gill slits are visible. On the right, white handwritten text reads, "HELICOPRION, heel-ih-coe-pry-on OR hell-ih-coe-pry-on, ~ means ~ "sprial saw"." The background is aloe green at the top, fading to a yellow-green at the bottom. This figure from Uhen (2004) depicts a black line illustration of the skull of Dorudon atrox, an ancient basilosaurid whale, in lateral right view, with the cranium disarticulated from the mandible. Many of the postcanine teeth in the upper and lower jaw have multiple cusps, unlike toothed whales today, which almost uniformly have simple, conical peg teeth. This figure from Erickson et al. (2012) depicts a dental battery from the hadrosaurid, Edmontosaurus. The left of the figure, with a black background, depicts a light pink line drawing of an Edmontosaurus skeleton (top left), a white illustration of an Edmonotosaurus lower jaw (middle left), and a color photo of part of the Edmontosaurus dental battery in the color of dark amber fading to citrine yellow at the bottom (bottom left). The right side of the image, which is relevant for the purposes of this post, depicts microsopic photos of the occlusal surface of a bison tooth and horse tooth alongside colorful labels showing features of these teeth (top right) and a photograph the teeth and part of the skull of Camptosaurus (bottom right).

Hadrosaurus foulkii, the first dinosaur discovered in North America and one whose holotype is housed at the currently-threatened Academy of Natural Sciences in Philadelphia. If the academy is shut down, this and thousands of other irreplaceable specimens will likely be lost. #SavetheAcademy #sciart
A colored-pencil drawing of the hadrosaurid dinosaur Hadrosaurus foulkii, in a walking pose at an angle away from the viewer and towards the left side of the page. Much of the body is a warm brown, separated by a darker squiggly line from the pinkish grey back. Its head is turned slightly towards the viewer, and a thin black tear marking extends down from its eye.

First, a bit of context on how animals & groups are given scientific names, and why certain suffixes can stick around when it comes to give names to new species

#Cheliceratime
2/4
Naming organisms 101 Although scientific names of organisms can seem weird sometimes (one of my personal favourites being the the wasp Aha ha), every single one of them need to have an meaning explicited in the publication first mentioning said name. Numerous rules, listed in the International Commission on Zoological Nomenclature for animals, rule how species & genera can be named in detail, while upper ranks often have greater flexibility (even tho families & sub/super ranks derived from it all have designated suffix). A species’ name is always binomial, having first the genus name, and then the species’ specific part. Naming organisms 101 Each given name is derived from pre-existing words (traditionaly latin and greek were often used but science is becoming more and more accepting of other linguistic origins to reflect science’s plurality), often chose to depict morphology, age, locality or particular feature. It can sometimes be a derivation of another species’ scientific name (like how the dinosaur genus Parasaurolophus was at first derived from another hadrosaurid dinosaur called Saurolophus), or be an hommage to someone’s name, as in Heteropoda davidbowie. However, it often happens that some suffixes are found in numerous related species’ names. Kokomopterus longicaudatus => “the fin of Kokomo with a long tail” Why use similar etymological roots? These similarities often reflect science history, as many groups were built on a species from which names of others were derived. They can also reflect past hypothesis (making scientific name an absolute treasure of knowledge in science history), like how Megarachne and Basilosaurus, both thought to be a spider and a reptile at first, are now respectively an eurypterid and a cetacean. The use of shared etymological roots is often an unsaid naming convention to give a group an identity of its own just with names. They can also be relevant to follow the methodology behind species’ identification, as numerous insects’ names are related to wing morphology and extinct mammals’ ones derived from teeth morphology. -arachne => Arachnida => Arachnopulmonata => Douglassarachne => Megarachne Why use similar etymological roots? Another butterfly effect is to sometimes ease the comprehension of scientific names by non-biology nerds: the recurrence of certain etymological roots, especially ones similar to common names, can be a huge help to understand quicker what an animal is just by looking at its name. As a science communicator (yup I’m gonna put my own thoughts here), it can be really helpful when talking to people about extinct and/or weird species, as it gives them mental checkpoints to understand at their pace new knowledge. -scorpio => Scorpion (common name) => Sardoscorpius/Gigantoscorpio/Pulmonoscorpius/Heteroscorpion (scientific names)
