New Brazilian Toothless Dinosaur Berthasaura leopoldinae

[Ikessauro]

On the news here in Brazil is a paper about a new species of Noasaurid theropod from the same fossil site as the pterosaur Caiuajara. This new dino was named Berthasaura leopoldinae and was a small, toothless animal. Exciting for me, as it's a new dino from my home state. Fairly complete too.

It's a juvenile, so it may not have been toothless as an adult, though it is a very interesting discovery, and one if the most complete of this year's dinosaurs named.

Well, the paper states "It most likely was a young sub-adult at time of death, comparable to ontogenetic stages 3 or 4 of Limusaurus inextricabilis".

I always understood that "sub adult" was an "almost" adult animal, older than a juvenile, but not quite fully mature. Maybe equivalent to a 17 - 22 year old human? Am I wrong in assuming this?

English is not my native language, so I might not be understanding it properly.

@Ikessauro when I commented that, I was going off a combination of secondary info, someone saying it was an infant on cisiopurple's page, and Gabriel Ugueto's artwork, but I've had a look at the paper and it is a sub-adult, and would be toothless as adult, the authors' suggesting herbivorous diet etc...
EDIT: Immature anyway, so I suppose could be juvelise, but probably just a not-quite fully grown individual. :END EDIT
So carry on, and sorry. I really need to read papers before commenting.

First off lucky you @Ikessauro to have something so interesting found so close by.

Secondly wow this is already one of my favorite discoveries this year. I mean just look at it! Love how near complete the remains are, immature status aside. Glad the paper is not paywalled either. While I'm already hoping for a figure of this down the line, I also hope its relative Limusaurus gets a figure made someday as well. Both are very interesting animals.

This is a cool find. Very lucky to have so much of the skeleton.
