Rediscovery of the type series of the Carboniferous ichnospecies Attenosaurus subulensis (Aldrich in Aldrich & Jones, 1930) and Cincosaurus cobbi (Aldrich in Aldrich & Jones, 1930) with comments on the designation of neotypes

摘要

The purpose of this note, under Article 75.8 of the Code, is to set aside the neotype for the ichnospecies Attenosaurus subulensis Aldrich in Aldrich and Jones, 1930. It was believed that the type specimens for Attenosaurus subulensis were lost; however, a recent search through the collections at the Alabama Museum of Natural History in Tuscaloosa led to the rediscovery of one of the two syntypes. Furthermore, the rediscovery of the syntype of the ichnospecies Cincosaurus cobbi Aldrich in Aldrich and Jones, 1930 should also be recognized. The discovery of a portion of the Attenosaurus subulensis type series negates the previously erected neotype.
