The American Crocodile
Transcript of The American Crocodile
By Rohit Geereddy and
The American Crocodile is found at the top of the food chain.
or prey?-Since the crocodile was at the top of the food chain it is easily classified as a predator.
or producer?-The American Crocodile hunted for its food other than producing it like a plant.
,herbivore?-The American Crocodile ate other animals as a food source classifing it as a carnivore.
: Usually lives in a group but can be found living by itself too.
:The diet of the American Crocodile consists of fish but it can eat crustaceans, turtles, and occasionally birds and mammals.
The crocodiles during the Jurassic period were mostly aquatic swimmers and lived in large bodies of water. They had flippers which helped them navigate through different areas in the water. When the climate started to change (after the Jurassic period) the oldest species of crocodiles (Tyrannoneustes) died out. Then during the cretaceous period the Deinosuchus came into the world. Some of the species that are related to the Deinosuchus were not that different in structure from it. Even the modern American Crocodile has almost the same structure. Somehow the crocodile were able to survive the extinction that killed the dinosaurs along with a very few other animals.
The age of the crocodiles started in the Triassic period. One of the first known species was known as the Tyrannoneustes.They thrived with the ocean life all the way until the Jurassic Period. When the climate became more dry and hot, the ocean depleted in size causing them to die. Then during the middle of the Jurassic Period a new type of crocodilian species emerged from the ground known as the Sarcosuchus. these creatures got used to the warm swamps where they began to hunt and catch prey.

Placement of the Geologic Time Scale
Eon found in:Phanerozoic
Era found in:Cenozoic
Period found in:Quaternary
Epoch found in:Holocene
Year of first appearance
It was first sighted in the late 1800's in Biscayne (just at the tip of Florida). The year of the modern day crocodile has still not have been found.
American crocodiles are found in coastal areas throughout the Carribbean. They live in brakish or saltwater areas. They can also be found in ponds, coves, and creeks inside mangrove swamps.
How Were They Related? Any Changes?
The ancient crocodile was a finned swimmer in the ocean. Today it is a creature that can move on land and water. Scientists have figured out that the most commonality of these reptiles is their tail and their mouth.Their tails always have scales, and their jaws are identical in shape and the interior design is perfectly alike. Over all the years that they lived on the Earth they only had a couple of major adaptations-Evolving from only water creatures to both water and land-dwelling and a major shrinking in size.
