Rhizocorallium

As Rhizocorallium is called horizontal ( = layer parallel to the surface ) or oblique to the layer surface of sediments and sedimentary rocks, U-shaped trace fossils, which have a so-called leaf blade in the middle.

Origin and tradition

The living marine generator is not preserved as fossils. The reason is that the trace fossil abbildete not the body of the producer, but only the trace left by this, probably in feeding activities or the like. It is believed that it (possibly cancerous animals) acted to sediment -eating creatures that have left these traces. A Rhizocorallium can for example consist of a central part, which is interpreted as housing and extending therefrom grave transitions.

Rhizocorallium has survived since the Cambrian to the present. It is a common trace fossil of the Mesozoic seas ( Triassic, Jurassic, Cretaceous ).

Possible classifications

Rhizocorallium is divided into three types, even if the classification is not controversial.

• Rhizocorallium Jenense
• Rhizocorallium uliarense

Classifications only affect the interpreted form of the Rhizocoralliums. The species of the tracking generator remains open, however, most authors lead them back to crustaceans.
