The ancestors of Terebratulina caput serpentis may have been present at a battle of Ichthyosauria in that part of the sea which, when the chalk was forming, flowed over the site of Hastings.

While all around has changed, this Terebratulina has peacefully propagated its species from generation to generation, and stands to this day, as a living testimony to the continuity of the present with the past history of the globe. Up to this moment I have stated, so far as I know, nothing but well-authenticated facts, and the immediate conclusions which they force upon the mind.

It has been very generally admitted by conchologists that out of a hundred species of this tribe occurring fossil in the Upper Chalk one, and one only, Terebratulina striata, is still living, being thought to be identical with Terebratula caput-serpentis.
Although there are eight or more species of Ammonites and six of them peculiar to it, this genus is much less fully represented than in each of the other subdivisions of the Upper Cretaceous group. Terebratulina striata, Wahlenb. Rhynchonella octoplicata, Sowerby. Upper white chalk. Magas pumila, Sowerby. Terebratula carnea, Sowerby. Terebratula biplicata, Brocch. Crania Parisiensis, Duf.
