| Ecospace Comments | LIFE HISTORY: Low-intermediate level tiering according to Bottjer & Ausich (1986); placed in intermediate-level epifaunal tier; stem lengths of 2-17 cm according to Brett (1984); majority of taxa would probably fall in intermediate tiering category. | |||||||||||||||||||||||||||||||||
