Physical Description

Kryptops was a short-snouted creature that grew to about 25-foot-long (7.6-meter-long) . Scientists have called it Kryptops palaios, or "old hidden face", because of the horny covering on its snout.
Kryptops had small, sharp teeth, tiny arms, and a horny face that may have helped the creature gobble its prey's internal organs.

Food Habits

Kryptops palaios, or "old hidden face," is thought have been a hyena-like scavenger that feasted on carcasses.
"From the texture of the [skull] bone it seems like they almost have a bill on the front of their faces for sticking their head in and gnawing away at carcasses," Sereno said.
"With such a short snout and such puny arms, Kryptops would not be so well designed for grabbing something that was trying to run away," he said.
Meanwhile the idea of a scavenging lifestyle for carnivores such as Kryptops is controversial, Lamanna said.
"If this thing had a fingernail-like covering all over its face, then maybe that was used to poke into carcasses, but I'd like to see more evidence for it," he said.
Prey - Kryptops likely targeted other large African dinosaurs such as the strange, long-necked plant-eater Nigersaurus, which had a muzzle resembling a vacuum cleaner.


Kryptops palaois & Eocarcharia dinops along with an even bigger predator, the fish-eating, sail-backed Suchomimus—represent a trio of meat-eating lineages that became dominant in Africa and possibly other southern landmasses, Sereno said.

Kryptops represents one of the earliest known abelisaurids, a group that was also found in South America and India, the researchers said.

Discovery

The dinosaurs were discovered in Africa's Sahara Desert by Paul Sereno, a paleontologist at the University of Chicago and a National Geographic Society Explorer-in-Residence.
