Sciurumimus Skeleton

Skeletal reconstruction of the newly described juvenile megalosaurid Sciurumimus from the Solnhofen limestone of Bavaria. Most life restorations depict a full, bushy tail, small head, longish legs, and stocky body, but the actual specimen shows the longest fibers are restricted to the anterior portion of the tail, the head is enormous, the legs short, and the body very shallow and slender, in keeping with its juvenile morphology. He's cute. The scale bar here is 50 cm.

May i make a prediction?
It will turn out this guy is a baby compsognathid (not because i'm opposed to feathered megalosaurs, far from it, but because this guy, especially in the skull department, is too much reminiscent of good ol' Juravenator ;)).

Awesome skeletal, though i'd guess he/she was also quite fluffy on his/her body... Sort of like a sparrow with a long tail and teeth!

Could very well be, on both accounts. Compsognathids may even be megalasaurs, or vice versa. Who knows?! The degree of fluffiness on this paritcular little guy could be either: 1) preserved in full, 2) preserved in part, 3) preserved in full, but he was molting/diseased, 4) a combination of 2 and 3. The vaguaries of fossil preservation and interpretation are ever-present!

I'm happy to hear that!

Hmm, are we sure this is a megalosaurid (or maybe a juvenile), instead of a very basal coelurosaur:? Nicely done, btw. :)

It's interpreted to be a megalosaurid by Rauhut and coauthors, so I'm just passing that along. Of course, it will undoubtedly change in the future as these things so often do. Being a juvenile, there's all sorts of issues in resolving phylogeny...witness the mess that is Raptorex!

This totally rocks my boxers.

I hope that's a good thing.

Presumably, yes. I'm impressed by your work.

The skull bones need some work. The squamosal and others toward the rear aren't so clear so I'll need to update the little guy in the future.

Do they know what era this is from?
Franz-Josef73's avatar
It's from the Kimmeridgean Stage of the Jurassic Period. About 151 to 152 million years old. Same as Archaeopteryx and Compaognathus.

I like their proto-feather crest on it's forehead. Good job.:)

Lots of baby birds have feather tufts on their heads so I figured why not.

Because it was cool.:suggestion:
