Sketch by Richter (1926) showing spreite in a Diplocraterion parallelum burrow.
Diplocraterion is an ichnogenus describing vertical U-shaped burrows having a spreite (weblike construction) between the two limbs of the U.[1][2] The spreite of fainter U-shaped traces appears above and below the final tunnel, made as the organism moved up and down through the sediment.[3] Diplocraterion is the classic example of an "escape burrow", where the organism moves upward during high-sedimentation rates, creating spreite below it, in order to prevent the burrow entrance from being buried.
