Rhizocorallium

High Quality Content by WIKIPEDIA articles! Rhizocorallium is an ichnogenus type of burrow, the inclination of which is typically within 10 of the bedding planes of the sediment. These burrows can be very large, over a meter long in sediments that show good preservation, e.g. Jurassic rocks of the Yorkshire Coast (eastern United Kingdom), but the width is usually only up to 2 cm, restricted by the size of the organisms producing it. It is thought that they represent fodinichnia as the animal (probably a nematode) scoured the sediment for food.
