I've been exploring dinosaur trackways this summer. Most of the Texas trackways are in the top of the Glen Rose formation and are likely from Acrocanthosaurus and Pleurocoelus.

Blanco Site Sauropod trackways on the Blanco River near Blanco, Texas.

San Angelo Site Permian trackways in San Angelo State Park, Texas. These trackways are actually older than dinosaurian. They are not very distinct, though numerous. The site can be hard to find. Bring water if you go in summer.

Glen Rose Site Dinosaur trackways near Glen Rose, Texas, in Dinosaur Valley State Park.

Leander Site These theropod tracks are in the South Fork of the Gabriel River 3 miles north of Leander, Texas. This is a very accessible site with a great single trackway of 11 tracks.

Hondo Creek Site This site is closed due to vandalism. (two miles south of the crossroads community of Tarpley, on FM 462)

San Marcos Site "Southwest of San Marcos the Trail highway travels precisely on the Balcones Fault, (42) illustrating its astonishing geographic demarcation. On the south side of the highway are dark, rich farm soils on a gentle landscape; immediately opposite is thin, rocky soil that barely covers the chalky slopes rising to the hills. The age difference between land on either side of the highway is at least 30 million years. After a short county-road segment, the route heads north on FM 306 toward one of the most attractive features on the Hill Country Trail--Canyon Lake. (43) About six miles north is Wildlife Wilderness, a drive-through exotic animal showcase. Your travel guide details the park and the preserved tracks at Dinosaur Flats, a feature of the Trail on FM 2673 along the south edge of Canyon Lake."

Boerne Site Theropod (Acrocanthosaurus) tracks along Cibolo Creek at the Nature Center at Boerne's Cibolo Wilderness Trail. This trackway is a cast from the originals that were in the Cibolo creek.

Austin Nature and Science Center, Zilker Park Walk out the back door and down into the small creek to view four really nice theropod tracks. These are similar to the ones at Leander. There are also some tracks at the botanical gardens in Zilker Park, but the area was closed to the public when I went to visit them.
