Hey guys, sorry it’s been a while! I have been busy with the exhibit, and I hope you understand. But without further ado….


The oldest fur seal has been described! Eotaria crypta was a small fur seal, around the size of a sea otter, and was minuscule compared to the other seals of its day, such as Allodesmus. The holotype consists of a partial jaw found in the 80’s that, until now, was thought to be from a prehistoric walrus. This small jaw was found in California and is thought to be around 16-17 million years old.

The earliest South American monkeys known to science have been described! Perupithecus ucayaliensis was the size of a tamarin, jumping from tree to tree around 36 million years ago! Because monkeys are not endemic to South America in the fossil record 36 million years ago, it took the team of researchers who described Perupithecus 2 years to realize that it was a monkey. Talk about monkey business!

Dippy is leaving! The iconic Diplodocus in the main hall of the London Museum of Natural History is being replaced by a Blue whale skeleton, and many people are not happy about it. Personally, I cannot say much as I have never been to the museum and seen the actual mount, but when I think London Museum, I think Carnegie Diplodocus. I agree with SV-POW! that the museum should put Dippy and Blue (my proposed nickname for the whale) side by side in the main hall.


LITC talks about the replacement of Dippy the Diplodocus and shows off some awesome artwork, which you can check out here. At Extinct Monsters, Ben Miller searches for the lost Missourium, a mastodon skeleton originally made by a showman. You can find that blog post here.


This week we have a photograph of the Gorgosaurus libratus skull which is on display at the Yale Museum.


Remember, if you would like to feature some of your artwork on this blog, comment below and we will she what we can do.

Thanks for reading guys!


    1. Thank you! (I am sure you know this but..) Gorgosaurus was slightly smaller and was more slender in build. If you like this skull, check out the one we have at my museum! It is included in the dinotopia post!


  1. I’ve been wondering about this for a while: could Albertosaurus and Gorgosaurus actually be robust and gracile morphs of the same species? If so, is it possible that one form traditionally identified as one species could be male and the other female? Sexual dimorphism in dinosaurs is not a new topic, and this might be just another example of it. Granted, I am nowhere near an expert on tyrannosaurid anatomy, and I am especially not an expert on Albertosaurus and Gorgosaurus – I think that THE Phil Currie has that base covered. However, I’d be interested in what you and other members of the paleo-community have to say about this.


    1. That’s an interesting theory. Originally they were thought to be of the same species, but more recent studies have shown them not to be. As for the possible sexual dimorphism, I’d have to look at the specimens more closely to form a valid opinion.
