Maldybulakia
Maldybulakia is a genus of freshwater arthropod which lived during Late Silurian to Late Devonian. Maldybulakia is known from three species, M. angusi and M. malcolmi from Australia, M. mirabilis from Kazakhstan, and M. saierensis from China. Its classification is uncertain, it was originally described as a myriapod-like animal, and later considered related to the xiphosurans, or an artiopod. Discovery and etymology In 1992, the type species of Maldybulakia is described from the Pragian to Emsian-aged Sheshen'karinskaya Formation (also known as the Sheshenkarinskoy Suite) in central Kazakhstan, with scientific name Lophodesmus mirabilis. The genus name Lophodesmus came from the Greek lophos ("tubercle") and desmos ("bond"), and the species name mirabilis means "wonderful" in Latin. However, this genus name is already used for an extant genus of myriapod, and in 1998, the new genus name Maldybulakia, named after Maldybulak Farm in the Bayanaul District, Pavlodar Region in Kazakhstan, was given to the animal. In addition, in 1998, two new species of Maldybulakia were described from two localities in the Devonian of New South Wales. M. angusi is described from the Lochkovian to earliest Pragian-aged Sugarloaf Creek Formation, M. malcomi is from Saltwater Creek Forest Road, usually regarded as Middle Devonian in
