Adding onto this. They were Coelophysis bauri, the "bog standard" Coelophysis, and Ghost Ranch is indeed the Late Triassic (they were contemporaneous with the Chinle Formation). The genus that is Coelophysis actually did make it into the Early Jurassic, in the form of C. kayentakatae and C. rhodesiensis (species formerly classified as |

I don't think we know for sure, since AFAIK all we have of Ankylosaurus is the skull, the end of the tail and a few osteoderms. |

i think 4 is probably the safer bet, its basal to Ornithischians. |

... We have trackways, you know. I'd have a pic or something if google weren't being annoying right now, but I assure you that they show that ankylosaurids had 5 fingers and 4 toes. |

Was Ornitholestes a basal coelurosaur or was it a basal maniraptoran? Also what was the environment of the Lourinha Formation like?

Ornitholestes was a basal maniraptoran IIRC. |

What were some of the larger examples of terrestrial "crocodilians" throughout earth's history. |

if we're talking about fossils definitely confirmed as Pseudosuchians, Fasolasuchus and other Rauisuchians were the biggest, I believe. Sebecosuchians got to quite large sizes too, as did Kaprosuchus and Mahajangasuchus. But if you take into account fragmentary material that may or may not be crocodyliform in origin, Razanandrongobe is by far the largest, at least as large as Tyrannosaurus. |

Thanks. Also was Yi Qi likely to be nocturnal or cathemeral? |

Nope,basal coelurosaur, related to coelurus and probably a very close relative of early tyrannosaurs. Some early analysis did put it close to the maniraptoriformes, but more thorough studies have put them closer to Juravenator, with both taxa being either early tyrannosauroids or sister taxa to them. https://en.wikipedia.org/wiki/Ornitholestes |

Oh, that explains why I see more reconstructions of it with protofeathers than pennaceous feathers. |

are those skin flaps thing connecting the crest and the neck speculative or do we have evidence for it? also, are there any knowledge on parasaurolophus's color and pattern? |

Incinerox said that they had a plain pattern to them IIRC as for the flaps I do believe they are speculative |
