PLOS Paleo Top 10 OA Fossil Vertebrates #1: Gualicho shinyae

We’ve made it! Coming in at #1 is an absolutely amazing dinosaur published this summer in PLOS ONE.

The study, led by authors Sebastián Apesteguía (Universidad Maimónides in Argentina), Nathan D. Smith (the Dinosaur Institute at theContinue reading “PLOS Paleo Top 10 OA Fossil Vertebrates #1: Gualicho shinyae”

Veggievore Fish of the Triassic

Fish have a bit of a boring reputation among many vertebrate paleontologists–too many bones, too hard to identify, not as charismatic as dinosaurs, etc., etc. But, this is entirely undeserved (and I say that as a dinosaur paleontologist, too)! The ins and outs of fish evolution are truly fascinating, bolstered by a phenomenal fossil record.Continue reading “Veggievore Fish of the Triassic”

Is a saber-tooth cat’s roar worse than its bite?

Maybe….if it’s cold outside. When the climate changes, organisms change with it. Environmental stresses can impact an organism by limiting ideal living conditions and/or decreasing prey, or can even cause favorable conditions that allow a population to flourish. These changes can be observed over time, whether it is a decrease/increase in numbers in a population,Continue reading “Is a saber-tooth cat’s roar worse than its bite?”

What a pain in the…arms! A record-breaking number of injuries in a theropod dinosaur

Ouch! That word came to mind a lot while reading a new paper published today in PLOS ONE. In the new paper, authors Phil Senter from Fayetteville State University and Sara Juengst from Appalachian State University, both located in North Carolina, describe the many injuries inflicted upon one poor Dilophosaurus wetherilli. And to be honest,Continue reading “What a pain in the…arms! A record-breaking number of injuries in a theropod dinosaur”

A Day in the Life of an Ammonite

Several years ago, back when I was working as the lab and collections manager for the St. George Dinosaur Discovery Site in St. George, Utah, we constructed a temporary exhibit with hundreds of ammonite shells from all over the world. One of our museum volunteers, an older French lady volunteering as a museum greeter andContinue reading “A Day in the Life of an Ammonite”
