In Depth

       After the release of its description,‭ ‬Kaprosuchus,‭ ‬or‭ ‘‬Boar Croc‭’ ‬as it is more often called,‭ ‬quickly captured the public’s imagination and entered popular culture soon after. ‬The name comes from the three sets of teeth that look like the tusks on a wild boar.‭ ‬These pairs of teeth are divided two pairs to the top jaw,‭ ‬one pair to the lower.‭ ‬The jaws also have notches in the bone to allow the teeth to pass through.‭ ‬Without these notches,‭ ‬Kaprosuchus would have had its jaws permanently held open by its own teeth.

       The tip of the snout is quite bulky and may have had a keratinous growth.‭ ‬Speculation for this feature has been for a potential battering ram,‭ ‬where Kaprosuchus would charge at its prey,‭ ‬stunning or knocking it down before clamping down with its jaws and teeth. The eye sockets are in a similar arrangement to other terrestrial crocodiles in that they are angled forward as opposed to upward.‭ ‬There is also enough‭ ‬of an‭ ‬angle to indicate the possibility that Kaprosuchus had stereoscopic vision,‭ ‬giving it a degree of depth perception.
