THE ROSETTED FEEDING TRACE FOSSIL DACTYLOIDITES-OTTOI (GEINITZ) FROM THE MIOCENE OF CATALONIA

The marine Miocene (Serravallian) deposits of El Camp de Tarragona (Ca talonia, Spain) have yielded many specimens of the rosetted trace foss il Dactyloidites ottoi (GEINITZ). The features that they show allow to recognize that D. ottoi is an endogenic feeding trace fossil with a c entral shaft and several branched radial elements with protrusive spre iten. The sedimentary environment where the rocks hosting the trace we re deposited in the studied outcrop, is very similar to those of other localities where the icknospecies has been founded formerly. So, D. o ttoi can be considered a good facies indicator for shallow marine, ene rgetic environments, usually in warm climatic conditions.
