Name:
Hecticoceras sp. Age: Jurassic Formation: Callovian Layers Location: Michailov, Russia Size: Largest ammonite is 2.4 inches across Price:SOLD
This is an absolutely beautiful block of ammonites. These ammonites are Hecticoceras from the Jurassic Period of Russia. There are three gorgeous ammonites clustered together on the large block of limestone, the largest being almost two and a half inches across. This type of ammonite has a distinct ribbing pattern, with mature specimens displaying subtle nodes - this feature is easily seen on these examples. All of the ammonites are extremely robust and exhibit very fine detail - even the tiny inner whorls of the ammonites are wonderfully displayed! The ammonites have brilliant natural coloration - they even retain the highly iridescent, mother-of-pearl shell (the rainbow of colors are much more vibrant in person than what the pictures show). The ammonites are beautifully showcased on the sculpted block of concretionary matrix. This is a fabulous display plate of unusual iridescent ammonites from Russia.
A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
