Spinosaurus
This is my attempt at reconstructing the skeleton of Spinosaurus aegyptiacus holotype specimen. If what we know about Spinosaurus is current, then this is truly an animal with bizarre features and strange proportions. The hind legs are very short compare to the length of the torso. The order of vertebral elements is speculative. Here I have followed the suggestion of Andrea Cau in his blog, placing the tallest neural process as an anterior caudal; while placing the dorsal centra with more bulging anterior face further up in the series. I chose the slightly up-tiled posture to show that the animal didn't have to be quadrupedal as suggested by Ibrahim. Scale bar is 1 meter.

Notocolossus
This is Notocolossus gonzalezparejasi, a giant titanosaur that is closely related to Dreadnoughtus. As you can see, its remains are rather incomplete; thus, this reconstruction is speculative.
The larger individual represents the holotype specimen. Not all haemal arches are illustrated. Scale bar is 1m per square.

Dreadnoughtus schrani
Dreadnoughtus schrani is another large titanosaur from Argentina. Although not being one of the biggest titanosaurs, it was still actively growing.
This drawing depicts what is assigned to the holotype specimen. The animal is 23-24 meters long by my estimation, and probably weight somewhere between 30 to 40 metric tons.
I extracted 3D data from the scanned and reconstructed skeleton, and modified the bones to account for crushing and distortion.
Scale bar is 1meter per square.

Edit
Adjusted the shape of the head and the angle of the scapula so the glenoid is more horizontal.

Got back from Massive Black art workshop in Seattle two days ago.
It's my first workshop and it was a blast. I met so many friends I've known from the forum, and so many amazing artists. It was a thrill to meet some of the best concept artists and illustrators in the business in person. Had a big party on top of the space needle, yeah, who's gonna forget that?
Fellow CA members, I know many of you are on devart. So if you happen to be my friend here and was at the workshop, leave a short responce, I'm trying to see how many of you are out there.
