Nice polished pieces of orthoceras to get a good look at their shell.
The Orthoceras were a group of cephalopods whose name comes from the Greek, orthos, straight and keras, horn; "straight horn".
This large "fossil squid" could measure up to 6 meters, they were quite developed invertebrates since they had eyes, jaws and a sophisticated nervous system. In addition, they had an external shell that protected them from predators.
In its diet were creatures such as trilobites, being a very voracious predator that was at the top of the food chain of its time.
The fossil includes a label with the name, period and provenance and is attached to a 4 cm square cardboard box.
*The price is per unit (a single cardboard box of the four shown in the image)
Since the samples are natural, you will receive a piece similar to the one in the photograph. The fossils come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the fossil. The size is approximate.
