Some unsorted sketches for the no-K/Pg project which have no text associated with them as far as I know.
(1) A member of a group of large, predaceous dromaeosaurs native to the Old World which have evolved congruently with carnosaurs or abelisaurs, with broad, flesh-rending jaws and reduced forelimbs.
(2) Two different species of South American kritosaurines, one with a large, colourful (just trust me), nasal crests which allow for powerful booming calls. The second is a coincidentally Ouranosaurus-like species. Note the lack of claws on the front feet, as they were designed before it was known.
(3) A member of a group of cursorial, browsing oviraptorosaurs (I think meant to be descended from Avimimus) common across the temperate regions of the planet. This is a more generalist, herd-dwelling, deer-like herbivore.
(4) A much larger, closely related species to the former, a towering high-browsing species with a cassowary-like casque and a body shape akin to the therizinosaurs (although without the huge clawed arms).
(5) A species of specialized burrowing thescelosaur (based on evidence of burrowing ornithopods like Oryctodromeus), I think this was some sort of North American, groundhog-like digger able to weather the winter climate, although I recall a prairie dog-like species was also considered.
(6) I genuinely am not sure what this was supposed to be. Some sort of thescelosaur or elasmarian, maybe?
