Teredolitesfrom the Garudamangalam sandstone formation (Late Turonian‐Coniacian), Cauvery basin, southeast India

Teredolites‐infested log‐grounds are abundant in the late Turonian‐Coniacian Garudamangalam Sandstone Formation in the Cauvery Basin, Southeast India. The morphological characteristics of the borings deviate from those of the ideal Teredolites clavatus Leymerie and Teredolites longissimus Kelly and Bromley, reflecting the response of the boring animals to substrate overcrowding and competition for space. Ichnological and sedimentological evidence indicate deposition of log‐bearing intervals in a delta‐plain or estuarine setting. Application of sequence stratigraphic principles indicates that log‐ground accumulation in the Cauvery Basin was closely linked to episodes of sea‐level rise (transgressive events).
