Teihivenator gen. nov., A new generic name for the Tyrannosauroid Dinosaur "Laelaps" Macropus (Cope, 1868; preoccupied by Koch, 1836)

Abstract


Once referred to the ornithomimosaur 'Coelosaurus' antiquus, 'Laelaps' macropusspecimens from the Navesink Formation (Late Campanian-Early Maastrichtian, Late Cretaceous) of New Jersey, USA was separated as a new species of 'Laelaps' by paleontologist Edward Drinker Cope in 1868. While it was revealed later that 'Laelaps' is preoccupied by laelapidae mite Laelaps agilis and renamed as Dryptosaurus, the taxonomic history of 'Laelaps' macropuswas controversial and sometimes considered as dubious. Here I show 'Laelaps' macropusas a valid taxon of tyrannosauroid based on comparisons with other taxa; there are considerable differences between 'Laelaps' macropusand Dryptosaurus aquilunguis. Therefore, a new generic name for 'Laelaps' macropus,Teihivenatorgen. nov. is erected here.
