What were some animals that lived alongside Ophiacodon?

It's the best I could find.

One note with Hartman's skeletals is that he shrinkwraps his outlines something awful, so be prepared to bulk the animal up a bit more than it suggests.

You may be mistaking some of Greg Paul's skeletals with Hartman's.

Hartman actually covers the minimum possible mass around his skeletal work. It's a good indicator of what kind of muscle mass could have been there, but there's definitely room for layers of fat and thick skin or simply beefier muscles. His older ones perhaps are a bit scrawny but he updates many of his older ones to fit new muscle mass models.

GSP however, really shrink wraps them royally. There's almost no space between the bones and the full outline for his stuff.

The truth is that skeletals in general tend to be more shrink-wrapped than life reconstructions simply because the skeleton is the focus rather than the entire animal.

That too.

It's mostly that the minimum muscle mass is the most conservative estimate for body shape. Once you start guessing how much fat or how thick the hide of an animal was, or start adding throat flaps or keratinous crests or spines or feathers, you start to fall within the realms of speculation. Going with the bare minimum is the safest outline to work with.

Which body type is more accurate for tusoteuthis?

Also I read in the book called "Dinosaurs of North America" it obviously predated the dinosaur Renaissance as most of the bipedal dinosaurs were still depicted like Kangaroos, but one article stood out they were describing the presence of Plateosaurus in North America based on fossilized teeth remains in Nova Scotia. Has any more information been revealed about this? It seems kind of interesting despite being somewhat outdated.

Prosauropod remains have been found in Nova Scotia, but they're not attributed to Plateosaurus these days AFAIK. Perhaps your book was referring to those.

They said and I quote "Fossilized tooth remains from Nova Scotia have been discovered which can be attributed to those of Plateosaurus"

But your probably right the book was written back in 1981

In terms of overall build, it appears you'd have something somewhere in the middle for Tusoteuthis. That said, the presence of hooks in mosasaur coprolites and guts suggest that these extinct squids didn't have sucker pads on their tentacles.

So the overall look would resemble a giant, but slightly gracile, Vampyroteuthis.

Have a couple of links. Hopefully they can help out more than I can right now:

https://www.tonmo.com/community/pages/tusoteuthis-cretaceous-giant-squid/

As for the Nova Scotia plateosaur, I've not managed to find anything on it, except for this:
http://earthsciences.dal.ca/aboutus/publications/theses/BSc/ES_2014_BSc_vanDrecht_Leigh.pdf

And I don't feel like it answers the question properly.

I didn't know they were aimed at only including the muscle mass, in that case I take it back about them being shrinkwrapped.

As per the Nova Scotia Plateosaurus, I know all of the local museums claimed that up until around 08, at which point most were changed to "uncertain prosauropod remains likely from Plateosaurus or a close relative".

What dinosaur species do we have the most fossils of for both carnivore and herbivore?
And how did Quetzalcoatluz grow so big in a land dominated by T-Rex? I understand how Hatezgopteryx got big but not Quetzalcoatluz

Simple. It didn't occupy the same niche. Quetzalcoatlus fed mostly on small animals, the kind of creature Tyrannosaurus was likely to ignore in favour of larger prey.

Quetzalcoatlus fossils are mostly found in the southwestern states anyway, where T. rex seems to have been less common.

We have evidence of a small (5.5m wingspan) Quetzalcoatlus individual from Hell Creek anyway.

It's reasonable to assume that they were widespread across the continent, but the more open landscapes (open enough for sauropods to exist in the south) probably favoured their way of life.

Minor speculation. The Hell Creek specimen is not a confirmed Q. northropi.
