Diplodocus (NOT Seismosaurus) longus

Description

I'm going to take a hard stance on this - there is no such thing as Seismosaurus, or even Diplodocus "hallorum". Nope, nada, never. It's a somewhat larger specimen of the also enigmatic D. longus (which is actually the type species for Diplodocus!), and there's nothing wrong with that. Long time viewers of my website (or of my professional publications) will know that this isn't a new skeletal, I've just updated it to current standards and decided to post it to DA since I haven't put anything up here in a while during a very busy summer.

Anyhow, for those of you who like such things, I've rechecked the scaling on everything (including the restored parts) and this specimen of D. longus is a hair under 32 meters in length, with is very respectable, though no where near the crazy estimates published in the 1990s.
