"This 1,523-acre park, a designated National Natural Landmark, was established primarily to protect the abundance of dinosaur tracks exposed in the riverbed of the Paluxy River, a tributary of the Brazos River. The bedrock consists of eastward-dipping limestones, sandstones, and mudstones deposited from 110 to 105 million years ago along the shorelines of an ancient sea. Black-capped Vireo and Golden-cheeked Warbler are monitored annually, and the park staff can provide up-to-date information on the best sites to see these two endangered species. Take care not to disturb them!
Key birds: Wild Turkey, Greater Roadrunner, Canyon Wren, Rufouscrowned Sparrow, and Lesser Goldfinch are present year-round. Common Poorwill, Chuck-will’s-widow, Black-chinned Hummingbird, Scissor-tailed Flycatcher, Black-capped Vireo, Golden-cheeked Warbler, Painted Bunting, and Dickcissel occur in summer. LeConte’s, Fox, and Harris’s Sparrows can usually be found in winter. This eTrail provides detailed information on birding strategies for this specific location, the specialty birds and other key birds you might see, directions to each birding spot, a detailed map, and helpful general information."
