EPD Spark-2 test: setting up a regimes for effective recovery of ammonites from silicified limestone

Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. The earliest ammonites appear during the Devonian, and the last species vanished in the Cretaceous–Paleogene extinction event. Ammonites are excellent index fossils, and it is often possible to link the rock layer in which a particular species or genus is found to specific geologic time periods. Their fossil shells usually take the form of planispirals, although there were some helically spiraled and nonspiraled forms (known as heteromorphs). Now we have approach for paleontologists as well as for collectors. #EPDSpark2 #fossilsrecovery #ammonites
