It is five feet long, 25-50 pounds, ate fish, and lived in the rivers of North America and western Europe. It had a long narrow profile and a tooth studded snout. It survived the K/T extinction.

Crocodylidae (Modern day crocodile)
55,000,000 bc - Present
The modern day crocodile, which includes the saltwater, Nile, and American variants, is spread throughout the world with various adaptions for specific climates and habitats. Though it looks prehistoric, it is a highly evolved and complex organism that is a successful predator.
23,000,000 bc - 40,000 bc
This animal was nine feet long and 500 pounds, and they consume red meat who they hunted in the woodlands. These crocodiles have long curved teeth and long legs, that are unlike the modern croc's short legs. andThe crocodiles continuously get smaller because of environment changes.
This is a very close relative of the modern day crocodile, it had a large scull and small raised rim in front of the eyes. It likely prayed on early humans. It lived in the Turkana basin in Kenya, and it could be the largest known true crocodile.
