Rhabdoglyphus from the Waynesville Formation of Waynesville, Ohio (OUIP 1797)

Published Description

Holland (UGA Strat Lab, 2013):

  • Repichnia (Crawling traces) – Rosary-like trails or tunnel fillings

Uchman (1998)

  • This ichnogenus was defined by Vassoevich for hypichnial cylinders composed of dense, partially invaginated calices. Boucek & Elias (1962) described under this ichnogenus hypichnial cylinders with rosary-like swellings. These specimens were separated by Rhabdoglyphus by Vialov (1971) as ichnogenus Fustiglyphus.

Treatise on Invertebrate Paleontology, Part W, Miscellanea Supplement 1 (1975):

  • Description: “Cylindrical tubes consisting of short, closely spaced, invaginated “calyces,” some with short branches; preserved in convex hyporelief.” W. Hantzschel 1975
  • Interpretation: Trail of uncertain origin; considered post-depositional by Ksiazkiewicz (1970, p 315-316). Fuchs (1985, p. 391) described “Rhabdoglyphen” from Australian flysch deposits, several of his forms similar to paper bags packed one inside the other.
