Rare Shocked Belemnite Megateuthis on Matrix
Ries Crater. Germany
The Nördlinger Ries is an impact crater and large circular depression in western Bavaria and eastern Baden-Württemberg.
It is located north of the Danube in the district of Donau-Ries.
The so-called Ries belemnites have been well known since geologists worked in the Ries region. Embedded in Jurassic marls and clays, the heavily dissected rostra were unquestionably linked to sudden strong deformation which, at the time of the volcanic hypothesis, was attributed to the giant diatreme explosion and later to the deformation of the impact shock. Therefore, fractured belemnites are frequently referred to as "shocked belemnites", although until now no explanation has been given as to how the particular dissections developed in fracture mechanics.
