Tetragramma donaldtrumpi is a species of fossil sea urchins discovered and identified by William R. Thompson Jr. in 2016.[1] The specimen locality is from the Lower Cretaceous, Trinity Group, of the Glen Rose Formation near Fischer, Texas, in the United States.[1] [2]
Based from the fossils discovered of Tetragramma donaldtrumpi, the species is known to have been about 1inches in size and round in shape, with the appearance of a Life Savers candy.[3] The genus Tetragramma is known from the Upper Jurassic (Oxfordian) to the Upper Cretaceous (Turonian).[4]
Thompson named the species to honor then Republican presidential nominee Donald Trump.[5] A paleontology lab at the University of Texas at Austin holds a fossil of the species, along with 45 other species.[3]
