Ampelognathus
Ampelognathus was a tiny, plant-eating dinosaur that lived in Texas about 96 million years ago. It was only about as long as a six-foot person and weighed as much as a medium-sized dog. This little dinosaur is known from just a single jawbone found near Grapevine Lake.1

Dintlha tse monate
Ampelognathus is the first small-bodied, plant-eating ornithopod dinosaur ever found in the Lewisville Formation of Texas.2
The only fossil known from Ampelognathus is a two-inch-long piece of its lower left jawbone.1
Its jaw has a twist: the back teeth point upward and inward instead of straight up, which is unique among its relatives.2
When Ampelognathus lived, a shallow sea split North America into two landmasses, and Texas was on the eastern shore with a hot, humid climate.1
The dinosaur was named after Grapevine Lake, where it was found, and honors Murray Cohen, the fossil enthusiast who discovered the jawbone.2
Ampelognathus is only the fourth named dinosaur from the Dallas-Fort Worth area, joining armored Pawpawsaurus and large Protohadros.1
