thalasinoides

Palaeophycus/?Thalassinoides, flattened cylindrical burrows, usually 5-25 mm in diameter. Straight or curved, surface rather featureless. Y shaped branching sometimes observed. Can often form a complex interlacing mass. They may be interpreted as dwelling or crawling traces of crustaceans.

a rare trace fossil


This is a rather rare trace fossil called Helicodromites mobilis. It is a horizontal helical spiral. As can be seen when sectioned, the spiral produced off-set circular sections are clearly visible in this example. That section is not central so three of the spiral sections are cut longitudinally. H. mobilis occurs in deep-water muds, but also in shallower settings as long as the seafloor is quiet and muddy.

condrites


Palaeophycus and Chondrites. Paleophyeus are flattened burrows from 5mm to 25mm in diameter. They are unbranched, straight or curved. Chondrites are 0.3to 0.6.. diameter, repeatedly dichotomously branching burrows. Abundant, often filling spaces between larger burrows. Has been interpreted as feeding burrow of a sipunculoid worm

TRACE FOSSILS

TRACE FOSSILS ARE SO IMPORTANT,FOR INTERPRETING THE PALEOINVIRONMENTS

Fossilized evidence of animal behavior, also known as ichnofossils, biogenic sedimentary structures, bioerosion structures, or lebensspuren. The fossils include burrows, trails, and trackways created by animals in unconsolidated sediment (see illustration), as well as borings, gnawings, raspings, and scrapings excavated by organisms in harder materials, such as rock, shell, bone, or wood. Some workers also consider coprolites (fossilized feces), regurgitation pellets, burrow excavation pellets, rhizoliths (plant root penetration structures), and algal stromatolites to be trace fossils. See also Stromatolite.

FOR GEOLOGISTS

THIS ARTISTIC WORK IS DEDICATED TO ALL POOR GEOLOGISTS WHO WORK NIGHT AND DAY TO UNDERSTAND WHAT IS RIGHT AND WHAT IS WRONG
