Name: Genicularia vertibralis
Species: Worm
Age: Oxford Clay, Jurassic
Location Found: Yaxley, United Kingdom

Genicularia vertebralis were annelids, or segmented worms, members of the Annelida phylum, as are earthworms.  Annelids have complex organs, including blood vessels, a nervous system, and a digestive tract; their bodies are formed of ringed segments. Worms’ soft bodies generally don’t fossilise, though traces of worms do fossilise. These are pieces of the calcareous tubes secreted by the marine worms. The Genicularia vertebralis worms living in these tubes were a free-living worm that was not physically attached to the interior surface of the tube in which it lived.  The interiors of these tube fragments are now filled with matrix.

ACTUAL AS SEENThe image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions.
