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.
