I believe that Dairu transforms into a veloci-raptor, which means that these things are cool way before Jurassic Park made them cooler than t-rexes....

According to TFwiki the robot mode is seems to be an Iguanadon. Is there anything on the box or inserts that indicates what the robot-dino mode is meant to be? I checked TF Generations, but it doesn't say.

Well it's missing the trademark thumb spikes of the Iguanadon so it'd be odd if it were to be that - It's proportions look far closer to that of an Omniraptor, though he doesn't have the beak of that dinosaur either.

I'm pretty sure dinosaur-spike-accuracy isn't something to go by with identifying the species of Transformer cassettes. According to his packaging, Overkill is a tyrannosaurus, and yet he does have a horn on his muzzle. (And now I think about it, Slugfest has a bump on his stegosaurus nose too.)

Indeed a fair point, but a funny one too because as you've mentioned - Overkill has a nose spike, which is horribly reminiscent of the misinterpreted placement of the Iguanadon's thumb spike when it was originally discovered.
Also, Trypticon is as much of a T-Rex as Sludge is a Brontosaurus - So I think you're dead right SS.

I might be wrong but isn't sludge a diplodocus?

No, you're dead right actually.
When Sludge was originally designed, he was modelled after a Brontosaurus but the Brontosaurus has been found to be a non-existent Dinosaur since (Whether it was misnamed, mis-identified or both I'm not sure), which is why he is now, at least by me, referred to as a Diplodocus.

*EDIT: Brontosaurus = Apatosaurus
From Wikipedia:

In 1877, Othniel Charles Marsh published the name of the type species Apatosaurus ajax. He followed this in 1879 with a description of another, more complete specimen, which he thought represented a new genus and species, which he named Brontosaurus excelsus. In 1903, Elmer Riggs re-examined the fossils. While he agreed with Marsh that Brontosaurus excelsus was likely a distinct species, he also noted many similarities between B. excelsus and A. ajax, and decided that both should be placed in the same genus. Riggs re-classified the species as Apatosaurus excelsus.[15] Almost all paleontologists since Riggs published his opinions have agreed that the two species should be classified together in a single genus. According to the rules of the ICZN (which governs the scientific names of animals), the name Apatosaurus, having been published first, had priority as the official name; Brontosaurus is considered a junior synonym and has therefore been discarded from formal use.

Hursticon, you were right in the first place about Sludge - he's a Brontosaurus Dinosaur Robo and thus has been retconned out of existence (or retconned into an apatosaurus as he was in Maximum Dinobots.)
