http://www.eartharchives.org/articles/the-stegosaur-lookalike-and-its-last-supper/ Things you need to know: -It had a stegosaur-like skull and ate cycads -5-6 meters long -Bajocian Argentina -The name is AWESOME, I don't care if it was named after its discoverer; seriously, Isaberrysaura. Is. A. Berry. Saura. It don't get better than that. |

Chilesaurus, you aren't the only "only one in its family South American Weirdo herbivore" anymore. being bipedal and the long face, it looks more like a theropod XD. |

At least this one's a herbivore in a herbivore clade. Chilesaurus is just a mess. That being said, stegosaurus look-alike? I dunno, I also get some strong Thescelosaurus vibes too. And THAT being said, perhaps the stegosaur-like skull is a result of convergent evolution. Both Isaberrysaura and stegosaurids are thought to have fed primarily on cycads. Such a diet may result in similar food gathering features in the skull. |

Funny you should say that, as one of the phylogenetic analyses performed found it to be a "parksosaurid" (i.e. a thescelosaurid), which as it happens was using the same dataset that placed Thescelosauridae outside of Ornithopoda and as a clade of neornithischians sister to Cerapoda. Cerapoda itself currently dates back to ~169 Ma, in which case Thescelosauridae would also be this old too, and Isaberrysaura just so happens to be ~169 million years old, give or take a million, so there's something to chew on. |

Honestly I'll be surprised if this thing doesn't turn out to be a basal Thescelosaurid or some bizarre branch-off of another basal ornithiscian group. |

So a group of small Bipedal bird-hipped dinosaurs that stayed small? I thought the small fry were ancestoral to Iguanadonts and Hadrosaurs... then again my info on theropods and later bird-hipped dinosaurs is better than early ones so pardon my ignorance. Would Thescelosauridae basically be the new Hypsilophodontia? Seems to the same to me, just renamed and rearranged with some stuff added or booted out. |
