A new anonymous User:65.93.24.168 has changed the extinction from 10,000 years ago to 8000 years ago. Is any one competent to vet this change and perhaps even expand upon why the date has been selected? --Wetman 22:37, 14 Jan 2005 (UTC)
Why are we talking about "the four species of ground sloth found in the United States"? A bit like discussing "Belgian dinosaurs" no? Why not North America? --Wetman 02:08, 13 Apr 2005 (UTC)
Which mainland is referred to in "on the mainland" (first paragraph)? From the discussion above I can only assume that this means North America, but "the mainland" is relative to where you are. I'm not nit-picking, it's just that I feel an encyclopaedia should be unambiguous to the best of the abilities of the contributors.
Only one ground sloth that I know of is actually found in Canada, Megalonyx. A good deal of the sloths in North America were only found in the U.S., but lets put North America just to be safe. Metalraptor (talk) 15:18, 1 December 2008 (UTC)
My personal opinion is that while it is good to have the distinctions between the different Epochs, the category of prehistoric mammals should still be included as many in the general public are unaware of which specific Epoch their mammal was from. Essentially, it would be like having two card catalog references. I agree that the Epoch distinctions are more accurate and if I had to chose one or the other, that would be the one I would keep. But I think there is still value in maintaining it. Or perhaps prehistoric mammals could become just a list of, provided all of hte current mammals ended up on the list. Any thoughts?

There's something wrong with the layout on this page. Does someone know how to fix it? Andrew Moylan 04:58, 11 February 2006 (UTC)
I doubt this idea would be feasible but does anyone have any thoughts on doing a map where we could put virtual pins on where such animals have been found? I think it would add to not only this but many of the long extinct animals. JohnCub 14:17, 13 February 2007 (UTC)
We really need to get started on changing all of the ground sloth family pages from redirects into their own articles.--Mr Fink (talk) 16:54, 23 January 2008 (UTC)
I've seen articles discussing the effects of the extinction of giant ground sloths on various plant species that benefitted from the sloth's presence in the form of seed distribution. I would like to request for someone to add this information if possible. Cazort (talk) 23:52, 5 June 2008 (UTC)
Yes to all split proposals. This is a natural. Umbertoumm (talk) 12:25, 18 August 2008 (UTC)
Scelidotheriidae needs to be merged back within Mylodontidae as the subfamily Scelidotheriinae. McKenna and Bell, which most of this list was created from, were invalid in their suggestion of a family level for the scelidotheres, and you'd be hard pressed to find any current fossil sloth researcher to agree with that elevation of status Doc Sloth (talk) 20:00, 28 March 2009 (UTC)
I'm not sure how to add a new footnote myself, but the statement "nearly every good specimen has been described as a different species" is cited in "Pleistocene Mammals of North America by Björn Kurtén, Elaine Anderson (Columbia University Press, 1980), as being from page 216 of Hirschfeld, S.E., and Webb, S.D. 1968. Plio-Pleistocene megalonychild sloths of North America. Bulletin of the Florida State Museum of Biological Science 12(5):213-96 --Anansii (talk) 23:45, 8 November 2008 (UTC)

Replacing xxx and yyy with the relevant details. Anaxial (talk) 23:53, 8 November 2008 (UTC)
The text contains two contradictory statements in regards to the phylogeny. In the "Megatheriidae" section, the first sentence says Megatheriidae and Megalonychidae together form the infraorder Megatheria. In the "Nothrotheriidae" section, the first sentence says Megatheriidae and Northrotheriidae together form the superfamily Megatheroidea. I'm not an expert in sloths, but I'm going to go ahead and alter this to say that all three families belong in the infraorder Megatheria.

Based on the activity on the Talk page, this article hasn't received a lot of attention in several years. I have a request, though. I am interested in ground sloth biology, but, like most extinct animals of South America, there are serious accessibility problems with data on sloths. One thing that bothers me is that there is virtually no accessible information anywhere that compares and contrasts the different sloth families. On this page, nothing at all is stated about the biology of any family: it only mentions if and when they appear in North America and some random anecdotes about what some paleontologists at some point speculated. It would be really helpful if somebody could provide some information about what distinguishes, e.g., megalonychids from megatheriids. — Preceding unsigned comment added by Tennesseellum (talk • contribs) 01:15, 5 September 2012 (UTC)
Should there maybe an artists interpretation of what the ground sloth looked like? It would be good to have an idea of what they looked like in life, which is hard for a layperson like me when just looking at their skeleton 123.243.215.92 (talk) 01:12, 22 June 2014 (UTC)
If we're going to have this section, would it be at all too much to ask for if its proponents could care to elaborate on discussing how ground sloths and their public perception have impacted "popular culture," and not leave it as a trivial laundry list of "spot the monster of the week" appearances?--Mr Fink (talk) 20:10, 16 December 2016 (UTC)

Article says that Clovis points were 'carved'. Apparently the writer knows nothing about flintknapping. You can't 'carve' flint, obsidian, and other similar stones with the materials peoples with neolithic technologies had access to. These points were rather pressure-flaked after the initial percussion used to prepare the cobbles to produce large blades from which the smaller finished products were produced. This is true espec~~ially of the long central fluting running down the length of the Clovis point from the tang to the tip. ~~ — Preceding unsigned comment added by 2601:89:C701:9190:B84B:5090:2420:8E9D (talk) 01:45, 22 April 2022 (UTC)
