Repenomamus is the largest mammal known from the Cretaceous period of the Mesozoic, and the only one with evidence that it ate dinosaurs.
Repenomamus is also larger than numerous species of Jurassic and Cretaceous birds, which are also considered dinosaurs by cladists.
Repenomamus is a genus of triconodonts, a group of early mammals with no modern relatives.

The skeleton of Repenomamus robustus was in a glass case in the foyer of the American Museum.
Repenomamus giganticus instantly became by far the biggest and baddest mammal of the dinosaur age.
Repenomamus robustus was about half the weight of Repenomamus giganticus, but the specimen had a feature which more than made up for that: shortly before its death, it had gobbled down a young dinosaur about 14 centimetres long.

 Dinosaur was dinner at least once, fossil shows / Mammal refused to be a victim -- ate psittacosaur
The intact remains of the dinosaur, called a psittacosaur, were found in the stomach of a mammal called Repenomamus robustus, which moseyed around China some 130 million years ago, scientists report in today's issue of the journal Nature.
The scientists also reported finding a larger relative of the mammal, Repenomamus giganticus, which is far bulkier than mammals of that era were thought to be.
Repenomamus robustus -- and even giganticus -- might sound pretty puny to us today, compared with wooly mammoths, whales and the other heavyweights of the evolutionary mammal kingdom.

 Scientists: global warming is causing spreading drought
The discovery of Repenomamus gigantus’s size combined with the discovery of the Repenomamus robustus fossil with the psittacosaur in its stomach recasts scientists’ understanding of Mesozoic animals.
Repenomamus robustus had large, pointy incisors, canines, and premolars useful for catching, holding, and ripping prey, further evidence that this group of primitive mammals ate meat as well as plants.
When initially naming Repenomamus, scientists combined the words reptile and mammal to refer to the curious shape of these “reptile mammals.” The resemblance to reptiles can be seen in their large, sharp, pointy teeth and short limbs that stick out from their bodies at an angle.

 Scotsman.com News - Sci-Tech - The dog that ate dinosaurs
About 100 million years ago mammals were thought to be at a distinct size disadvantage in the face of predatory dinosaurs, only reaching the size of rats and mice, weighing a few pounds at most and spending the majority of their time trying not to be eaten.
Named Repenomamus giganticus, the creature is thought to have weighed up to 30lb, resembled a large dog and been big enough to compete with large dinosaurs for both food and territory.
The last meal of the Repenomamus robustus specimen turned out to be a baby psittacosaur, a two-legged, parrot-beaked, plant-eating dinosaur which could grow to nearly 6ft tall, and was common in the area of China where the fossil mammal was unearthed.

The first fossil, the size of a large cat and dubbed Repenomamus robustus, was found to have the remains of a young parrot-faced dinosaur, a psittacosaur, in its stomach.
Indeed, the term "Repenomamus" ("reptile mammal") was coined to express the odd aspects of these creatures, which had large, sharp and pointy teeth and reptile-like limbs that stuck out from their bodies at an angle.
A Repenomamus could waddle, although not run, and could stand on its hindlimbs and walk effectively enough to stalk small prey.

 Repenomamus - the mammal that ate dinosaurs
Dating to the Lower Cretaceous some 130 million years ago, the discovery of the mammalian fossil of Repenomamus giganticus renders to a myth the generally accepted hypothesis that Mesozoic mammals were cowering, nocturnal creatures that slinked about by night staying clear of the dinosaurs that ruled the land.
Concurrently, another mammal now named Repenomamus robustus, some half the size of Repenomamus giganticus, was uncovered at the same site with the bones of a baby Psittacosaurus in where its stomach would have been.
The disarticulation of the Psittacosaurus suggests that Repenomamus tore its prey apart prior to devouring it, consistent with the mammal's sharp teeth and lack of molars.

The skeleton of Repenomamus gigantus, found in China is a prime example of their large size.
The skull of this creature is fifty-percent larger than the skull of Repenomamus robustus, which was previously believed to be the largest mammal of the Mesozoic Era (2).
The recent discovery of the largest known mammalian species Repenomamus gigantus, along with the discovery of dismembered, presumably digested dinosaur remains in the fossilized skeleton of Repenomamus robustus represent dramatic changes in the perception of mammals from the Mesozoic Era.

The bones' articulation also suggests that Repenomamus tore its prey limb from limb before gulping it down in large chunks, Hooker argues.

A scientist at the Museum of Natural History, New York, points to the remains of a young dinosaur in the stomach of the fossil of a mammal called Repenomamus robustus.
Most mammals of the Mesozoic era, between 144 and 65 million years ago, were the size of today?s mice and rats, weighing a few pounds at most.
The Repenomamus had jaw muscles, and large, pointy teeth useful for catching and ripping prey, suggesting that these primitive mammals ate meat as well as plants and were aggressive predators, rather than scavengers.

Such evidence, according to researchers, suggests that Repenomamus did not chew its food and was a powerful, aggressive predator rather than a scavenger.
The last meal of the Repenomamus robustus specimen turned out to be a baby psittacosaur, a two-legged, parrot-beaked, plant-eating dinosaur which could grow to nearly 6ft tall, and was common in the area of China where the fossil mammal was unearthed.
It was highly likely that Repenomamus giganticus had a similar diet, the scientists said.
