Contradiction

Is it a skeleton or is it an animal?

195.194huiti76rfo76t7650 17:00, 23 January 2006 (UTC)[reply]

Both, but starting the discussion with the skeleton is wrong. I see no reason to have the sentence about one species being maroon either. That's like starting a page on vertebrates with a comment on yellow-bellied sapsuckers. Consider both fixed. --205.160.180.136 13:19, 13 April 2006 (UTC)[reply]

It would classify more as a rock since it is made out of sand and is not a living being.

doves?

Some info about the "doves" would be nice. I have some pictures here: [[1]]. Apparently they form the equivalent of a jaw. --CTho 02:52, 5 August 2006 (UTC) In a living sand dollar, the five "doves" fit together to form a star-shaped structure called the Aristotle's Lantern. The doves are joined by muscles that contract to bring the pieces closer together to crush sand grains. Each dove has a tooth that bisects the structure.[reply]

Please don't merge!!!

Please don't merge!! It is like merging Mallard with Duck!! :o --HoopoeBaijiKite 21:00, 18 June 2007 (UTC)[reply]

I agree, I've removed the template from both pages. The request was made by an anon user anyway. Jack 17:59, 22 July 2007 (UTC)[reply]

Pansy shell redirect

I've made a redirect page of Pansy shell to here. I hope I'm right in assuming that they are the same thing. I know Pansy shell may not be recognised as a proper name for them, but tourist areas of Southern Africa like to call them that. Jack 17:56, 22 July 2007 (UTC)[reply]

Information on Paleozoic/Mesozoic Sand Dollars

Do we have references or even genus names of the Silurian sand dollars? I can not find anything about "Silurian sand dollars" beyond whatever the mirror systems are copying from the wikipedia article. All of my sources tell me that the first sand dollars diverged from the sea urchins during the ~~Eocene~~ Cenomanian Epoch of the Cretaceous.--Mr Fink (talk) 22:43, 3 May 2009 (UTC)[reply]

Bad Link

Who is the * who inadvertently linked "podia" to the article on podiums (singular of one definition of "podia")??? People, check where links will go to before you write them in! —Preceding unsigned comment added by 98.232.230.111 (talk) 00:30, 1 October 2009 (UTC)[reply]

Sea Biscuit

Sea Biscuit, the Clypeaster rosaceus seems to have been lumped in here. Is this article about the whole Clypeasteroida order, of which Sand Dollars are one family member? Group29 (talk) 02:04, 28 December 2009 (UTC)[reply]
