Tshekardocoleidae
Tshekardocoleidae is an extinct family of beetles, known from the Permian. They represent amongst the oldest beetles. Like other primitive beetles, they are thought to have been xylophagous. They first appeared during the Cisuralian, before becoming extinct at the beginning of the Guadalupian. A claimed Jurassic record is doubtful. The oldest known beetle, ''Coleopsis,'' was originally assigned to this family, but is now assigned to its own family Coleopsidae.

Coleopsis
''Coleopsis archaica'' is an extinct species of stem-group beetle. It is the only member of the genus ''Coleopsis'' and family Coleopsidae. It is known from a single specimen from the Early Permian (Asselian) of western Germany, estimated to be about 297 million years old. It is currently the oldest known beetle. Taxonomy and systematics While originally interpreted as a member of the family Tshekardocoleidae, this interpretation has been revised and questioned, with the most recent analyses suggesting that it is best placed in its own family, and may be the sister group to all other beetles. The family name was originally published in 2016 as "Coleopsidae" but a later publication claimed that this spelling was erroneous and proposed the spelling "Coleopseidae";Kirejtshuk, A.G.

Boris Rohdendorf
Boris Borisovich Rohdendorf (russian: link=no, Борис Борисович Родендорф, 12 July 190421 November 1977) was a Soviet entomologist and curator at the Zoological Museum at the University of Moscow. He attained the position of head of the Laboratory of Arthropods, Paleontological Institute of Russian Academy of Sciences, Academy of Sciences of the USSR (now Russian Academy of Sciences) in Moscow. A student of Andrey Martynov, he was a prolific taxonomist who described numerous new taxa, including fossil Diptera Flies are insects of the order Diptera, the name being derived from the Greek δι- ''di-'' "two", and πτερόν ''pteron'' "wing". Insects of this order use only a single pair of wings to fly, the hindwings having evolved into advanced ..., and published important syntheses on fossil insects. His work is being extensively revised by the current generation of Russian paleoentomologists. Partial bibliography * Rohdendorf, B.B. 1937. iptera ...

Noble County, Oklahoma
Noble County is located in the north central part of Oklahoma. As of the 2010 census, the population was 11,561. Its county seat is Perry. It was part of the Cherokee Outlet in Indian Territory until Oklahoma Territory was created in 1890, and the present county land was designated as County P. After the U. S. government opened the area to non-Indian settlement in 1893, it was renamed Noble County for John Willock Noble, then the United States Secretary of the Interior.Dianna Everett, "Noble County." ''Encyclopedia of Oklahoma History and Culture''. Retrieved October 3, 2013. History During the 18th and 19th centuries, the area now occupied by Noble County was used as a hunting ground by the Osage Indians.

Artinskian
In the geologic timescale, the Artinskian is an age or stage of the Permian. It is a subdivision of the Cisuralian Epoch or Series. The Artinskian likely lasted between and million years ago (Ma) according to the most recent revision of the International Commission on Stratigraphy (ICS) in 2022. It was preceded by the Sakmarian and followed by the Kungurian. Stratigraphy The Artinskian is named after the small Russian city of Arti (formerly ''Artinsk''), situated in the southern Ural mountains, about 200 km southwest of Yekaterinburg. The stage was introduced into scientific literature by Alexander Karpinsky in 1874. Base of the Artinskian The base of the Artinskian Stage is defined as the first appearance datum (FAD) of the conodont species '' Sweetognathus whitei'' and ''Mesogondolella bisselli''. In order to constrain this age, the ICS subcommission on Permian stratigraphy informally proposed a candidate GSSP in 2002, later followed by a formal proposal in 201 ...
