The Trachyceratidae makes up part of the superfamily Trachyceratoidea along with such families as the Buchitidae, Distichitidae, Dronovitidae and Noridiscitidae. Fossil record Fossils of ''Trachyceratidae'' are found in marine strata from the Devonian to the Triassic. Fossils are known from many localities in Afghanistan, Canada, China, Europe (Slovenia, Spain, Switzerland, Ukraine), India, Japan, the Russian Federation, Thailand, and the United States. Description Trachyceratid shells are more or less involute and highly ornamented. They have their whorl sides covered with flexuous ribs that are usually tuberculate. The venters generally have a median furrow bordered by rows of tubercles or continuous keels.

The Devonian ( ) is a period (geology), geologic period and system (stratigraphy), system of the Paleozoic era (geology), era during the Phanerozoic eon (geology), eon, spanning 60.3 million years from the end of the preceding Silurian period at million years ago (Megaannum, Ma), to the beginning of the succeeding Carboniferous period at Ma. It is the fourth period of both the Paleozoic and the Phanerozoic. It is named after Devon, South West England, where rocks from this period were first studied. The first significant evolutionary radiation of history of life#Colonization of land, life on land occurred during the Devonian, as free-spore, sporing land plants (pteridophytes) began to spread across dry land, forming extensive coal forests which covered the continents. By the middle of the Devonian, several groups of vascular plants had evolved leaf, leaves and true roots, and by the end of the period the first seed-bearing plants (Pteridospermatophyta, pteridospermatophyt ...
