 Description:
This ammonite is known as Anetoceras. It has an eye-catching
form. The ammonites are either involute, in which successive
whorls overlap each other, or evolute in which they do not. This
is a more extreme form of an involute in that the successive
whorls both increase in size and increase in separation in what
is known as a gyrocone. This gyroconic form, as well as the ribbing
make this a most aesthetic example. Much time was spent preparing
the whorls free of matrix as you see it here. |
