I read an article a while back that compared what the writer considered to be the most likely ancestors to T.rex. According to the article, Daspletosaurus is the most likely ancestor to T.rex. The article had some pretty interesting points about anagenisis, and how D. torosus probably evolved into D. horneri, and that the entire lineage ended with T.rex. One of the more interesting things I read was that a lacrimal bone was found in the Judith River Formation, and it was thought to be from T.rex. The article said that Daspletosaurus had eye sockets more similar to T.rex than Albertosaurus or Gorgosaurus, and because of this was likely an ancestor. This sounded reasonable to me, but I understand you can’t trust everything you read online, and I wasn’t sure what the current scientific consensus was on the ancestor to T.rex.

I got this tooth mixed in with a bunch of small Moroccan stuff and it struck me as something a little different. To me it bears a striking resemblance to Palaeocarcharodon, without the serrated blade. It doesn’t look right for Otodus or Cretalamna to me, it’s too delicate and thin, very much like Palaeocarcharodon. Any thoughts or suggestions on it identity would be appreciated. Happy newyear!
