The 100-mm-wide fossil consists of one and three-quarters whorls and about 61 preserved teeth. Due to weathering, the rest of the fossil was lost and the preserved section is distorted from slippage of the host rock.[1] While initially differentiated using the metrics of tooth angle and height, Tapanila and Pruitt considered these characteristics to be intraspecifically variable, reassigning H. ferrieri to H. davisii.[2]
