Bowengriphus is a freshwater organism known from Late Permian deposits in Rangal Coal Measures of eastern central Queensland, Australia

It was originally interpreted as a relative of Odontogriphus , but a re-analysis of this fossil discounted any relationship, placing the fossil as incertae sedis . [2]

It is a small (≈15 cm), elongate, soft-bodied bilaterian as the body is bilaterally symmetrical, with a rounded anterior region and a tapering posterior. Its most distinctive feature is a double-looped feeding apparatus with paired rows of conical elements, integrated into the anterior region. No segmentation, limbs, or mineralized skeleton are present. The fossil shows a single, continuous body plan without evidence of separate appendages or external armor.
