Taenidium irregulare Li, 1993

Description: Freely curved meniscate burrows with intermeniscate segments generally longer than wide, and even more deeply concave menisci; burrow ranging irregularly from 0.7 to 1.2 cm in diameter. Discussion: As compared with Tacniditm cameronense (Brady, 1947), this new ichnospecies has even more deeply concave menisci, with the burrow changing irregularly in width.
