Because crocs have small stomachs and because parts of the animal tend to fly off when it is being thrashed by a crocodile , large sections of the carcass are often left behind nearly untouched. After the crocs had fed, Jackson collected the remaining bones, cleaned them, and examined and catalogued the marks left on them.
While many of the marks made by crocodiles were similar to those made by mammalian carnivores, some were distinct. Crocodiles have pointy, conical teeth with sharp ridges, called carinae, at the front and back.
These teeth often but not always leave behind impressive punctures and distinctive pits with a deeper gouge running through the center, called bisected marks. Crocodiles also sometimes produce curved scratches, called hook-scores, which may reflect their violent feeding behavior.
Of course, not all of the marks were so clear cut. Crocs also inflict deep, thin scratches, deep gouges, and fields of narrowly spaced grooves on bone surfaces. Fortuitously, Jackson found other clues that point to crocodile predation as well.
Mammalian carnivores frequently gnaw on bones, but crocodiles do not. Click to see full answer Also to know is, how many teeth do crocodiles have?

Because many adults have had their wisdom teeth removed, it is common for many people to have only 28 teeth. Usually all adult teeth have formed and erupted into the mouth by the time a person is 21 years old except for the wisdom teeth , which sometimes don't have space to erupt. Crocodiles are large reptiles found in tropical regions of Africa, Asia, the Americas and Australia.

Run for Your Life. Toothy grin: When their snouts are shut, crocodiles look like they're flashing a toothy grin, as the fourth tooth on each side of the lower jaw sticks up over the upper lip. For alligators , the upper jaw is wider than the lower one, so when they close their mouths, all their teeth are hidden. Jaguars like water Unlike lots of big cats, they don't avoid water. Actually, they are fairly fond of it and are good swimmers also.
