Happy #MosasaurMonday!
For an animal as common in museums as mosasaurs (> 4,000 specimens in N.A. alone), you may be surprised to hear that there are still 2 *fundamental* unanswered questions about them: what are they, & how many times did they become marine?
a #scicomm 🧵... Image We know that mosasaurs are lizards, & everyone agrees that within lizards, they're non-iguanian toxicoferans. Beyond that, however, there are 2 leading hypotheses: mosasaurs are either most closely related (1) snakes OR (2) monitor lizards. The root cause of this ambiguity...

While I'm 'celebrating' by making final tweaks to the ND critter manuscript, it occurred to me that there's something very important we don't actually talk much about in paleo social media circles: how *do* you describe a new species, anyway?
Time for a 🧵! A disarticulated skull of a... Perhaps unsurprisingly, properly identifying & diagnosing extinct species is incredibly tricky! For starters, because they are, necessarily, dead & gone, we cannot use many of the same species concepts we use for living animals (e.g., whether individuals interbreed)

Last week, #Thalassotitan was making news for exemplifying what mosasaurs did best: killing anything & everything that lived alongside them! 🦎🔪
A 🧵 of fossil evidence for murder by mosasaur jaws...

#paleontology #scicomm #fossils Image First, let's talk about the new kid on the taxonomic block: Thalassotitan! It belongs to a group of mosasaurs called Prognathodontini, all bruisers with insanely powerful jaws & massive, serrated conical teeth - NOT adaptations for making friends!

Undergrads & new grad students - NOW is the time to start thinking about applying for the @nsf GRFP!
A thread of advice I've accumulated on how to write a successful application...🧵

1/20 I applied to the NSF GRFP twice, & was successful the 2nd time; I chalk up that success to my advisors at RGGS, Carthage, & Marquette, & so most of the advice below comes from them.
