did allosaurus lived in same era and same continent with styraco ?


Lythronax

Allosaurus lived in the same continent, but not at the same time.

Styracosaurus coexisted with Gorgosaurus libratus and a tyrannosaurid related to Daspletosaurus.

How about velociraptor and carnotaurus ?  :)

Velociraptor lived in Asia 75-71 million years ago.

Carnotaurus lived in South America 72-69 million years ago.

So they did not coexist with each other and neither coexisted with Styracosaurus.

I want to make my next hand made diorama, now im looking a model to accompany my papo styraco :D

Wikipedia can be a good source for info like this.  They have entries on a lot of fossil formations including lists of what species were found together there.

Styracosaurus lived alongside Gorgosaurus libratus, Daspletosaurus "chicagotyrannus", Troodon inequalis, Dromaeosaurus albertensis, and I think Saurornitholestes langstoni.

As far as I know, Albertosaurus is known from the younger Horseshoe Canyon Formation, which means the ceratopsians it coexisted with were Anchiceratops, Arrhinoceratops, Eotriceratops, Pachyrhinosaurus (P. canadensis, and P. lakustai), and the as-of-yet unnamed "Almond Formation" ceratopsid.

Actually, and very weirdly, Albertosaurus doesn't seem to have coexisted with ANY ceratopsids.
https://en.wikipedia.org/wiki/Horseshoe_Canyon_Formation#Biostratigraphy

It appears in the fossil record in the HCF right after Anchiceratops and Pachyrhinosaurus become absent from the region (Anchi presumably becoming extinct, Pachy moving north and evolving into P. perotorum alongside Nanuqsaurus.)

There seems to have been some kind of faunal turnover here. I would speculate that a yet-unknown tyrannosaurine probably lived alongside Anchi and P. canadensis and evolved into Nanuqsaurus as it followed them north. Edmontosaurus also disappears from the HCF at this time. The whole fauna seems to have shifted up to Alaska and been replaced with Albertosauus, Saurolophus, and Hypacrosaurus.

Another faunal shift happened later with the arrival of Eotriceratops (evolved from Ojoceratops in the south, then evolved into Triceratops) probably accompanied by the ancestors of T. rex and Edmontosaurus annectens that drove albertosaurs out.

That is odd. It looks like Eotriceratops arrived just before the extinction of Albertosaurus, but still throughout basically the entire time it existed there, there were no ceratopsians.
