Scaphites is a genus of cephalopod mollusk belonging to the Ammonites. Unlike most of the Ammonites, it had a shell uncoliled. He lived between the lower and upper Cretaceous (between 110 and 94 million years ago). Its remains are found in much of the world, particularly in Europe (England, France) and in North America.
The appearance of this small ammonite was definitely curious: the shell was in fact partially coiled, with a front U-shaped, thick and swollen, with a particular symmetry. The general form is called scafitoid (from the name of this animal) and presented the first turn coil closely umbilicated; subsequent rounds, however, were unrolled in a slightly curved stick and, in the end, it fell back to the starting point.
The ornamentation of this ammonite was made up of smooth or ribbed collated with knots; the region of the stick has less dense ornamentation. The head of the animal, probably protruded from the shell with a considerable angle.
Like other ammonites of the Cretaceous, Scaphites presented a regressive form, both as regards the spiralizzation both for sutures simplified. Because of the particular shape of the shell, it seems that this ammonite was not able to exercise an active swimming, probably filled with water the various rooms to go up or down along the water column, leading a kind of planktonic life.
It is possible that Scaphites was closely related to other warned of more traditional look, as Kosmoceras. Other Ammonites uncoiled, with look vaguely similar (Macroscaphites, Ancyloceras) may not have been close relatives of Scaphites.
