Talk:Hadrocodium

Endothermia/Body Size?

The article currently implies doubt that this species was endothermic, evidenced by a statement that warm-bloodedness is a disadvantage when combined with a small body size. I'm not a biology expert, but the average body size of modern endothermic mammals and birds seems to indicate that whatever tradeoffs are necessary to maintain both warm-bloodedness and small size are well worth it. --Raphite (talk) 05:38, 25 November 2007 (UTC)

I used some of the information in the Science article documenting the discovery of Hardocodium to clean up the article, added a pointer to the article itself, and removed the cleanup box at the top of the page. It doesn't mention anything about the endothermy vs. ectothermy question, but I think it's reasonable to reword in a less suggestive way the text you point out.

More tweaks needed

Peter M. Brown, I hope I clarified the "45 mya issue". According to Luo et al 2001, p. 1537:

This extends the first appearance of these modern mammalian features back to the Early Jurassic, some 45 million years earlier than the next oldest mammals that have preserved such derived features, such as Triconodon from the Late Jurassic.

Yes, thanks. Peter Brown (talk) 18:30, 16 April 2013 (UTC) (Fama Clamosa comment continued below)

The article still needs some work. The "endotherm group" paragraph is not correct for example. --Fama Clamosa (talk) 17:16, 16 April 2013 (UTC)

Please speak to a recognized professor and then pay from your pocket a great painter and upload many great pictures

If you don't want to pay, don't do it that way. Some people pay for science. Please do not upload juvenile or amateur junk! — Preceding unsigned comment added by 2A02:587:4103:C400:21F0:7830:5040:77CC (talk) 20:42, 21 April 2017 (UTC)

Can it really be proven that this is a Mammal?

" making it one of the smallest mammals ever." this cannot be proven cause the there is only the skull. the rest is speculation. I would suggest the term mammalian rather than mammal. "Hadrocodium are capable of laying eggs like today's platypus and echidna." How can that be proven? -steph — Preceding unsigned comment added by 2003:D1:472A:18C4:2145:4A62:118F:2AA9 (talk) 17:05, 28 December 2019 (UTC)
