DESCRIPTION: Discrete ovoid borings in bone. Hollow, oval chambers with concave flanks bored into inner spongy and outer cortical bone surfaces. Chamber length three to four times greater than diameter. May be isolated, but observed more commonly in dense, sometimes overlapping concentrations. Walls roughened commonly, composed of shallow, arcuate (apparently paired) grooves.

BEHAVIOR(S): Reproduction (calichna)

ENVIRONMENTAL SETTINGS: Bone in continental terrestrial environments.

POSSIBLE TRACEMAKERS: Such insect larvae as dermestid beetle or tineid moth larvae

GEOLOGIC RANGE: Jurassic–recent

REMARKS: Named for Cretaceous borings in dinosaur bone. May appear similar to Gastrochaenolites. They represent necrophagous insect larvae laid as eggs by the adults on a carcass during the dry putrid or post-decay stage of decay while on the surface and above the water table.
