Our Mission

Seymour, Texas is famous for it's permain red beds, which date back to 287 million years ago! That is 40 million years older than dinosaurs, which is the biggest reason to why the animals we dig up right here in Seymour, Texas is so important. So, if they're not dinosaurs  what are they? The things we dig up like Dimetrodon the famous fin-backed animal are called non-mammalian synapsids (mammal-like reptiles). These animals are the very first animals to walk on land and stay on land without having to go back to the water, which makes them very important. We are actually more related to Dimetrodons than we are to dinosaurs! Scientists have been digging here in Seymour since the late 1800's, but they have been taking their fossils to other museums all over the world. We even have an amphibian named " Seymouria" that was discovered right here in Seymour   by German paleontologist Ferdinand Broili in 1904. All the fossils that have been found here have been taken away , that's why the Whiteside Museum is here. We want to educate everyone about Permian fossils and keep them in the town they were discovered in, and hopefully inspire others who want to pursue paleontology or volunteer to help with the museum.
