Description
You can't always get what you want and I certainly didn't want a new installment in the Jurassic Park franchise. Good thing not watching Jurassic World is the easiest thing to do. In any case, it came to my attention that there's a hashtag on Twitter predicated on one-uping the uninspired creature design for the movie's apparent boss monster, I-rex.
So here we have an omnivorous relative of Chilesaurus, though more inclined toward hard food items. I think the best ecological comparison would be with an entelodont. If you fancy an extant one, I don't think a wild boar would be far from the mark. Possibly a facultative quadruped, the posture of this whichever-size-you-think-is-most-scary animal was inspired by the description of its real life relative's hand, showing a well-formed third metacarpal but only an nubbin of a phalanx associated with it. It's my impression that, along with the rather robust ventral portion of the pectoral girdle, this means that Chilesaurus's arms bore weight with regularity. So I don't think it unreasonable that the lineage would develop a knuckle-walker along the way.
Another aspect of this work is it being an attempt to abbreviate my process. I'll let others be the judge of how successful I was in that effort as, for now, I can only see the faults...
