Which US state is frequently cited as yielding significant Permian freshwater shark finds of Xenacanthus?
Answer
Texas
Specific geographical areas have proven exceptionally fruitful for paleontology in locating remains of Xenacanthus. Texas is prominently mentioned as one region where significant fossil finds occur. The Smithsonian National Museum of Natural History specifically highlights Xenacanthus as a Permian freshwater shark originating from this particular state. This localized concentration suggests that certain fossiliferous beds found within Texas have provided exceptionally rich deposits capable of preserving these fragile aquatic remains, likely due to ideal geological and depositional circumstances present in central North American craton areas during the Permian.
