It looks like a mini iguanadon with a really big tail. Neato.

Cool! I love simiosaurs.

Weird critter... looks like a photograph!

Very funky. I like how you made the tail an "immitation leaf" and not the "sculling organ" envisioned by the original authors. Right or no, this looks more on the line of plausible than the improbable swimmer when it was published!

I just love your drepanosaurs (or simiosaurs). :) Great work!

I was thinking Hypuronector might have been aquatic (or semi-aquatic), because it seems to be much less adapted for arboreal life than its ofter relatives.

It depends on what you mean. Just because a reptile has a deep tail doesnt mean it's aquatic.

Aquatic tails, like those of crocodiles and sea-reptiles are also wide and muscular at the base, and generally fairly flexible.

Many reptiles have flat or deep tails that are comparatively weak and stiff, and are simply used for camouflage. This was the case with Hypruronector, it's tail-bones are thin and delicate, and relatively inflexible. This would make it a very poor swimming organ.

Also, it's lesser adaptations to climbing may simply indicate a sedentary lifestyle. Sloths have comparatively puny muscles today, and no gripping digits, but spend almost their whole life in the trees. Their ancestors however were massively muscled and lived on the ground somewhat like dinosaurs. Similarly, a lizard with energetic climning skills, like a monitor, is far more muscular than a sedentary gecko.

Yeah, I think you're right after all.
My only reference for Hypuronector has been a simple skeletal drawing that really doesn't tell much about the wideness or flexibility of the tail (or at least I don't have the skills to interpret that). If tail wasn't flexible, it probably isn't a swimming device.

Hypuronector also seems to have much less robust limbs than the other simiosaurs, but it might, of course, be because of the more sloth-like habits. Though sloths seem to use their long claws to hang from the trees and thus don't need gripping digits, and your Hypuronector doesn't have anything like that. Am I right to assume that the digits are actually unknown?

not sure, if they are, they were not described. Any that were even preserved would take ages to interpret.

You imagine its huge tail as leaf camoflage, eh? Interesting take.
