I have been sitting on this guys concept for ages trying to put him together just right and pick a goddamn good name for him. I remembered quite a while ago that my childhood Digimon had gone from gecko to frilled lizard to dimetrodon to spinosaurus. The names were ever so creative - Gekimon, Frillmon, Dimetromon - but heaven help me if I was going with "spinosaurusmon" or "spinomon" or whatever the hell else you could come up with by shoving the suffix "mon" onto spinosaurus. So I dug around and spinosaurus has a lot of cousins, but like zero with the big distinctive spine, and "ostafrikamon" and "irritatamon" don't have the ring I was going for. Like, at all. So I went with the superfamily of megalosaurus and added the "ad" to kind of tie it into Megalodon, the bigass shark since I was working with trying to make him look sharklike. Considered giving him a shark tail like I did with Dimetromon but that felt like overkill.
But Digimon stats:
Undetermined Type (water? earth? fire? I don't even know, can't decide)
