I have edited the page somewhat as megacheirans do not have a bivalved carapace, nor are they particularly crustacean-like. Severan (talk) 13:47, 12 May 2011 (UTC)Reply

Yohoia edit

I just put earliest=Middle Cambrian because of Yohoia.

Then Yohoia was a mistake. — Preceding unsigned comment added by 98.177.220.111 (talk) 03:28, 23 January 2013 (UTC)Reply

Suggestion to merge "Great appendage" into this article edit

While the terminology is somewhat confusing. "Great appendage" is solely used to refer to the appendages of megacheirans, as opposed to the term "frontal appendage" used to refer to the appendages of gilled lobopodians and radiodonts. Having two articles on essentially the same topic is somewhat redundant, and neither article is anywhere near big enough to warrant the separation. We already have an article on the Arthropod head problem to discuss disputes surrounding anatomical homology of arthropod heads. Hemiauchenia (talk) 22:00, 12 November 2022 (UTC)Reply

support This looks like a great way to expand the context on this article. Joyous! | Talk 23:10, 14 December 2022 (UTC)Reply
