Fossil record
editFossils 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.[1]
Description
editTrachyceratid 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.
