Incomparable Russian Ammonite on Stand

Tropaeum sp.
Upper Aptian
Volga River Area, Ulyanovsk central Russia

In Tropaeum, the body chamber can touch the previous whorls or can be separated and loose so that it forms a hook-like shape. Only the ammonite family is capable of this phenomenon. The present specimen is an example of the body chamber that touches the previous whorls. The suture patterns are visible in the growth chambers with some of the mother of pearl still present on the living chamber. This is a very large specimen for the species. Mounted on a custom metal stand. Measures 20 x 17 x 6in
