Record #101273:

Silurian Archaeoscyphia from the Canadian Arctic: a case for simplified generic taxonomy in the anthaspidellid lithistids (Porifera) / Tim A. de Freitas.

Title: Silurian Archaeoscyphia from the Canadian Arctic: a case for simplified generic taxonomy in the anthaspidellid lithistids (Porifera) / Tim A. de Freitas.
Author(s): de Freitas, Tim A.
Date: 1989.
In: Canadian Journal of Earth Sciences. (1989.), Vol. 26(10) (1989)
Abstract: On basis of specimens collected on Cornwallis Island, argues that Archaeoscyphia exhibits continuous morphological variation and therefore that four formerly proposed separate species should be synonymized.
