Prehistoric badass: Fossils of giant Texan shark discovered

The shark fossils were recovered in 2013 from the Lower Cretaceous Duck Creek Formation of Tarrant County, north-central Texas. They then were analyzed by a team of paleontologists led by Dr Joseph Frederickson from the University of Oklahoma, Norman.

“These vertebrae represent a single animal of approximately 6.3 m (20 feet 8 inches) in minimum total length, making this individual one of the largest documented sharks from the Early Cretaceous of North America,” Dr Frederickson and his colleagues wrote in a paper published in the journal PLoS ONE.

The scientists hypothesize that these fossils belong to the prehistoric lamniform shark Leptostyrax macrorhiza (lived between 145 and 100 million years ago) based on their size and co-occurrence in two typical localities.
