[edit] Premolars vs Molars

I believe that there are no molars in "milk" teeth - only premolars. The molars erupt at a later date. Is this the case?

[edit] list of dentition patterns of North American mammals

I found a table on the internet from a good source that seems to have the dentition patterns of all the mammals of North America.

  1. Is this a good place to put such a list?
  2. Can I put something like that from a webpage into wikipedia?
    1. Do I need to reference where I got it?
    2. Do I need to paraphrase the text part that lists the names of the species?

1) From what I gather is on the table, yes. (2) Yes, if the webpage is a reliable source. (2a) Yes, reference would be helpful. (2b) Paraphrasing would be better and perhaps mandatory to avoid copyright issues, though prose would be preferred to mere lists. I am interested to see this webpage. - Dozenist talk 03:23, 1 September 2006 (UTC)
I don't think it meets the reliable source criteria. I prefer not to put the link here now that I see the author says no one can use his information anywhere else on the web.

What I could do is start with one species from each dentition configuration and find a reliable source that verifies for each, hopefully for more than one at a time. Then I could start a table here with that. Other species could be added to the table as they are found. He doesn't own the information after all.

We could also have tables for mammals from the rest of the world.

Email me if you would like to see the link. I tried to send it to you but couldn't. -Crunchy Numbers 04:25, 1 September 2006 (UTC)

[edit] Dental Formulae

It is more accurate to say that the primitive, rather than the maximum, dental formula for placental mammals is 3/3 1/1 4/4 3/3. Cetaceans, for example, frequently have many more teeth than the "maximum" referred to in the current verbage. In a similar way, we should be sure to say that the primitive dental formula for marsupials is 5/4 1/1 3/3 4/4. Tomwithanh 05:53, 24 April 2007 (UTC)
