Hello and welcome to I know Dino.

I'm Gareth.

And today we'll be talking about allosaurus, as well as a lot of dinosaur news.

We're back from our trip to Europe, where we had the opportunity to see a lot of interesting dinosaur museums.

For those of you following us on social media, we posted a few pictures on our Twitter and Facebook feeds.

And this is our 25th episode, which we're recording on Saturday, May 16th.

First in the news, there's a new quarry that was discovered in Montana called J-R-D-I-5-E-S quarry.

I guess it doesn't have a cool name yet. It's just known by that scientific nomenclature.

And the unique thing about it is they found a set of Stegosaurus that appear to show differences between the genders. So specifically, the Stegosaurus in this area is called Stegosaurus Moose, and if you read it,

the moose part is spelled M-J-O-S-I, and that's named after the man who collected and prepared

the holotype of that species.

The study was published in the PLOS-1 journal, which we've mentioned before, and they're

quick to point out that it's very difficult generally to find differences between genders of

dinosaurs, especially because there are a lot of differences just between species and within a

species. So a lot of times, if you're looking at different specimens,

especially if they're in different areas,

you're not sure if the differences between the specimens

is because they're different species

or they have some other variation that's not related to their gender.
