ANYWAY - wish I had some or could find some, but there aren’t many out there. You can find the jaws and skulls at Scientific Illustration. An interesting point about the 3-chambered/4-chambered heart of the crocodile can be found here, if you didn’t already know that fact.
Most of the crocodilian is bone and cartilage. The only part that has major muscle development is the tail, but boy does it ever. Still, I can’t find any illustrations of the tail muscles, so if anyone out there has some, feel free to point me in their direction.
