In 1835, after a thorough study by William Clift and William John Broderip, this report, strongly expanded, was published in the Transactions of the Geological Society, describing and naming the fossil as a new species.
Nakon detaljnog istraživanja koje su 1835. proveli William Clift i William John Broderip, taj izvještaj, jako proširen, objavljen je u Transakcijama Geološkog društva, te je u njemu opisan i imenovan fosil nove vrste.
