Scientists on Wednesday announced the discovery of an ancient, mammal-like crocodile that knew how to chew, something its modern gash-and-gulp cousins can't do.

The 100-million-year-old reptile, unearthed in Tanzania, was about the size of a domesticated cat and more at home on land than in water.

It had an unusually lean profile, a flexible backbone and relatively little scaly armor around its midriff, the better to leap in the air to grab giant dragonflies and other airborne prey.

But the most bitingly distinctive feature of Pakasuchus kapilimai, the researchers said, was its choppers.

It shared the overhanging, fang-like canines that today's alligators and crocodiles use to rip into their victims' flesh before swallowing them more-or-less whole.

But it also had specialized teeth that looked suspiciously like the molars once thought to be unique to our distant warm-blooded ancestors.

"At first glance, this croc is trying very hard to be a mammal," quipped Patrick O'Connor, a professor at Ohio University in Athens and lead author of the study, published in Nature.

"A number of characteristics of this new species are very similar to features that were critical during the course of mammalian evolution from the Mesozoic into the Cenozoic," which began 65 million years ago, he said in a statement.

The discovery adds to a growing body of evidence suggesting that crocodiles were once far more diverse than they are today in body type, habitat and appetites.

The diminutive croc would have co-existed with carnivorous theropods such as Tyrannosaurus rex and Velociraptor, as well as the huge, plant-eating Sauropods.

O'Connor and colleagues found a complete skeleton of Pakasuchus in Tanzania's Rukwa Rift Basin in 2008, and have also recovered portions of seven different individuals.

The new crocodile's name comes from "paka", the Swahili word for cat, and "souchos," Greek for crocodile.

Questions:

1. How old is the reptile?

2. Where was it unearthed?

3. What does the crocodile’s name of “paka” mean in Swahili?

Answer:

1. 100-million-year-old.

2. Tanzania.

3. Cat.
