This is the skeleton of an Australian Vlad Quadrodile, a species I created 10 years ago and have expanded to have sub species, an island, prey and predators, and realistic anatomy.

I used some real life animal skeletons for reference on different sections and combined some in parts that no animal has.
Head, neck, tail, are reference off crocodile skeleton studies. The tail and head being partially combined with kangaroo.
Arms and legs were referenced from kangaroo skeleton studies.
Middle section spine based off canine and kangaroo skeleton studies.
I originally started this a few months ago but it turned into a bigger project than expected, next will be the muscle structure.
