Brachiopod with healing worm scars

Submitted by: David Thompson
Taxon: Paraspirifer bownockeri, Cornulites
Submit date: 2011-05-04
Location (approximate): Sylvania, Lucas, OH
Stratigraphy: Silica Formation
Age: Erian (Middle Devonian)
Submitter notes: This large brachiopod was infested by the worm, Cornulites, at an early stage. It also shows the tiny holes of the boring sponge, Clionoides, along what was once the lip of the Brachiopod. What is unusual here is that the worm died before the Brachiopod as the tube is truncated and the brachiopod continues to grow with a healing scar. The Brachiopod is 4.1 cm high by 5.9 cm wide.
