Fossil Friday: Prosalirus

chibi_Prosalirus

 

Species: Prosalirus bitis (Pro-sah-lee-rus bee-tis)

What it means: Leaping forward

Where I live: Arizona in the U.S.A.- The Kayenta formation

When to find me: The Early Jurassic period, about 196 million years ago.

My favorite food: Bugs! I’m an insectivore.

My neighborhood: The Kayenta formation used to be a tropical floodplain, a bit like African savannah today- but no grass or flowers. Ferns cover the open plains, dotted with islands of spiky cycad groves. Rivers crisscross the land with lush tree ferns, ginkgo trees, and conifers. Every year during the wet season the plains turn into a flooded marsh, but the hottest months bring no rain, and the rivers shrink until the plains are almost as dry as the great desert that lies to the north.

A few of my neighbors: Since I’m a tiny, froggish guy, I have to watch out for all sorts of predators like Dilophosaurus, Kayentavenator, Coelophysis (meat-eating dinosaurs), and crocodile cousins. In the sky, flying pterosaurs with long tails would love a snack. More friendly neighbors are Sarahsaurus (an early sauropod), Scelidosaurus (armored dinosaur), and Scutellosaurus (smaller armored dinosaur). I like to hang out on the riverbank with the turtles and keep an eye out for insects like beetles, dragonflies, an ancient cousin of the moth, and something called a snakefly.

Fun Fact: I am one of the very first frogs, and the first frog we know that could actually jump! Most of the tail my ancesters had is gone, and my legs are a bit shorter than modern frogs.

Put your hand up to the silhoette. It should be life size!

  1. Great! Cool to see Prosilarus, an amphibian, get a debut on the site, probably the first time it’s mentioned on a the main part of a webpage on WordPress. I’d like to see one (probably called Silas) on a COTM page. I remembered the suggestion of Vieraella before and I’m glad we get to see an amphibian on the site. I want to know, what’s your opinion on it, Patricia?

    1. Hi! thank you so much! I’m glad you like the little guy. 😀 It was very interesting to do research and find out more about it, since I know absolutely nothing about prehistoric frogs. It was cool to find out that it’s the first truly jumping frog that we know of. 🙂 I don’t think it’s a “true frog” though.

      I completely forgot about Vieraella, but if it’s the first “true frog” known it’ll certainly find a place in Pete’s Petshop at some point. That’s an important traight! 🙂
