Just down the road from the local Starbucks, a rich trove of 95-million-year-old dinosaurs, sharks, and other prehistoric beasts—and their feces—have been unearthed in Arlington, one of Texas's biggest cities (map), researchers said this week.

Together the fossils help flesh out the very different Texas of the Cretaceous period, which lasted from 146 to 66 million years ago (prehistoric time line).

The discoveries include a new, unnamed, mid-size species of theropod, part of the two-legged, predatory dinosaur group that included Tyrannosaurus rex. The site also contains the most complete skeleton to date of a Protohadros, one of the earliest known duck-billed dinosaurs.

Crocodiles, turtles, fish, and parts of ancient plants and trees—including a 6-foot (183-centimeter) log—were also found.

At the time, Arlington would have been on a low-lying coastal plain. Here, swampy bogs transitioned gradually into shallow seas—a place not unlike the Mississippi River Delta today (map).
