Nigritrachelorex

Nigritrachelorex, a large carcharodontosaurid, lived in the Cretaceous, 99-66 mya. So far, 4 species with 10 specimens have been discovered. During 2033, scientists uncovered a large femur bone they decided belonged to a theropod. The scientists called it a new type of Spinosaurid, named Spinodryptosaurus and named the species S. piscis, for fish. Then soon found out, after a complete skeleton of a carcharodontosaurid was discovered during the december of 2045. Scientists renamed the animal "Gigacarchsaurus" in late 2046. After 10 more years of study, they found another skeleton of the species N. Magna, the largest Nigritachelorex species, and named it "G. piscis". A famous scientist, the same one who discovered Traumatonyx, found N. Regulus and renamed the whole genus "Nigritachelorex". Later the same year, some archaeologists digging around in Europe found "N. Katastrofi".
