The holotype specimen of Paratypothorax, SMNS 5721, consists of a series of articulated osteoderms alongside a few hip and leg bones.

It has been found in the Sonsela Member of Petrified Forest National Park in Arizona, as well as the Bluewater Creek Formation of western New Mexico.

[2][4] Osteoderms of Paratypothorax have also been reported from the Norian-age Fleming Fjord Formation in Greenland,[5] the Zarzaitine Series of Algeria, and an unverified occurrence in India.

[6] Paratypothorax possesses paramedian scutes that are wide, strap-like, and have grooves and pits on them forming radial patterns.
