Scolicia

Scolicia de Quartrefages, 1849 is a parataxon of ichnofossils present in sedimentary rocks of marine, marginal lacustrine, alluvial, or fluvial facies.

These fossil traces appear in a wide geological range, from the Cambrian to the present.

[1] Scolicia traces appear as horizontal, bilaterally symmetrical, meandering trails, variably shaped, ridgelike or ribbon like, about 1-5 centimeters wide.

The trail consists of two parallel and identical in width stripes with variable trasversal ribs and a central channel.

[1] When these traces do not have the transverse ribbing their realization is usually assigned to members of various groups of gastropods and crustaceans.

Scolicia strozzii ( Savi and Meneghini , 1851), trails made by echinoids about 65-40 million years ago (from Italy)
