Tototlmimus Packardensis
''Tototlmimus'' is an extinct genus of ornithomimid dinosaur. Its remains were found from the late Cretaceous Packard Formation, in the Sonora state, México. Discovery The only known species, the type species ''Tototlmimus packardensis'', was formally described in October 2015 by Claudia Inés Serrano-Brañas, Esperanza Torres-Rodríguez, Paola Carolina Reyes-Luna, Ixchel González-Ramírez and Carlos González-León; because the online publication was not registered in ZooBank, the name was only validly published when the paper was printed in March 2016. The genus name is derived from the Nahuatl word ''tototl'', "bird", and the Latin ''mimus'', "mimic" (from Greek μῖμος). The specific name refers to its origin from the Packard Formation. The fossil specimen, holotype ERNO 8553, was found in the northeastern Mexican state of Sonora, in the Cabullona Group, in a bed of the Packard Shale which may date from the late Campanian, 72 million years ago. It consists of a partia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campanian
The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian. The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks. Etymology The Campanian was introduced in scientific literature by Henri Coquand in 1857. It is named after the French village of Champagne in the department of Charente-Maritime. The original type locality was a series of outcrop near the village of Aubeterre-sur-Dronne in the same region. Definition The base of the Campanian Stage is defined as a place in the stratigraphic column wher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
