CIRCULICHNIS LEOMONTI, A NEW RING-LIKE ICHNOSPECIES (TRACE FOSSIL) FROM THE LATE CAMBRIAN LION MOUNTAIN MEMBER, RILEY FORMATION, BURNET COUNTY, TEXAS

Abstract

AbstractCirculichnis is a well-known ichnogenus demonstrating broad stratigraphic and geographic distribution with known habitats spanning from deep-marine to terrestrial environments. Although commonly small in size, a recent discovery in Central Texas demonstrates a much larger early member of this ichnogenus. Compared to previous identifications of Circulichnis, the findings presented herein express a larger trace string width exceeding the average for this ichnogenus. This expansion in morphometric parameters emphasizes the importance of overall dimensions in ichnospecies descriptions in concert with descriptive taxonomy.
