Description
Simple vertical burrows without special lining; smooth or regularly annulated; openings may be funnel-shaped; not crowded. [Dwelling burrow; e.g., Tigillites habichi LISSON (1904, p. 41) (Jur. or Cret.; S. Am., Peru) is U-shaped burrow with spreite and type species of Polyupsilon HOWELL, 1957, p. 151 (according to GOLDRING, 1962, p. 238] [Junior synonym of Diplocraterion TORELL); whether Tigillites is to be regarded as a synonym of Skolithos HALDEMAN, 1840, or Monocraterion TORELL, 1870, has been under discussion for more than a century-see SALTER (1864b, p. 289), BOUC:EK (1938, p. 249), PENEAU (1946, p. 78), HALLAM & SWETT (1966, p. 103), SEILACHER (1969a, p. 118, 122); thorough studies of many specimens of these three ichnogenera are required before questions of synonymy will be resolved.]
