My best guess is it will be a G1 version of an AOE Dinobot, the most highprofile of "add on" Dinobots. And of the two it'd be most likely Scorn, who is in the movie and a big dinosaur, rather than Slash, who's not in the movie and a small dino.

A spinosaurus transformer would be not too disimilar to a T-Rex, and LER-04 and LER-05 look like they have similar body shapes.
Best guess I've seen is Slapper. Club weapon, doesn't really look like a Sludge-type body-shape (i.e. probably not a remold, which makes sense cost-wise), with visible non-flipper-y feet on the bot-mode arms in the silhouette.
There is this not-Sludge remold from Mechaform though.
