On graduation, he join the research group of Professor Stanley Westoll at the University of Newcastle upon Tyne, working on the fossil reptiles of the Late Triassic found in Elgin.
Among many other achievements, he was the fist to name and describe the Upper Triassic Chinle Formation, which is famous for preserving extensive fossil evidence of Late Triassic terrestrial ecosystems, including fossilized logs.
In the Hochkalter and Hocheis Groups, the harder Dachstein limestone predominates, rock that was formed by sedimentation in the Tethys Ocean during the Late Triassic stage (220 million years ago).
The mountain range formed at the northern edges of the Cimmerian Plate during its collision, in the Late Triassic, with Siberia, which resulted in the closing of the Paleo-Tethys Ocean.
It was collected in the Otis Chalk Quarry 2 (TMM 31099 locality) from the Colorado City Formation, Chinle Group, dating to the early Carnian stage of the Late Triassic, about 228-227.5 million years ago.

The genus was named for Coburg, Germany, the type locality where specimens have been found dating back to the Late Triassic.
The fossils came from a mudstone next to a river channel deposit, in Lithofacies Association II of the Deep River basin, part of the extensive Newark Supergroup, dated as pertaining to either the late Carnian or early Norian faunal stages of the Late Triassic.
It is known from a skull roof impression found in the Ashfield Shale (Late Triassic) of Mortdale, New South Wales, Australia.
It contains a single species, Stenomyti huangae, which is known from a skull, postcranial skeleton and other referred material from the Late Triassic Chinle Formation, Eagle Basin of Colorado, USA.
In 2003, Adam Yates published a study incorporating these and other fossils from the Late Triassic of Germany.
