Long before humans, thousands of species of dinosaurs ruled the earth — even inhabiting what we know today as the Lone Star State. Texas contains evidence of over 36 species of prehistoric reptiles that date back as early as the Permian era, nearly 300 million years ago. Fossils and footprints can be found in five national and state parks in Texas. Government Canyon Natural Area, the only public area in Bexar County containing dinosaur footprints, is located right here in Northwest San Antonio. In conjunction with its Louis A. and Frances B. Wagner Series, the Witte presents “From Dinosaur Bones to Footprints: Over 100 Years of Fossil Discoveries in Texas,” a dino-namic discussion led by Dr. Thomas Adams, curator of paleontology and geology. Brush up on the history of dinosaurs in Texas as Adams references the larger-than-life Acrocanthosaurus and Tyrannosaurus Rex skeletons on display along with footprints and fossils of these ancient reptiles. The lecture comes after the recent unveiling of an impressive new museum extension that includes the Naylor Family Dinosaur Gallery and an interactive Dinosaur Lab offering visitors a hands-on paleontology experience. $5-$10, 6:30-8:30pm Wed, Apr. 12, Witte Museum, 3801 Broadway St., (210) 357-1900, wittemuseum.org.
