Talk:Hyopsodus

I cannot find any uses of "tube sheep" prior to 2007 in Kirk Johnson and Ray Troll's "Cruisin' the Fossil Freeway". They gave no source in that for their nickname. I saw it in the NPS pages for National Fossil Day for this year, but aside from pages cloning Wikipedia, I just can't seem to find it anywhere else. Has anyone else seen this elsewehere? I'm not certain this nickname is ubiquitous and I think it probably shouldn't be on Wikipedia if it can't be demonstrated as such. 71.236.93.51 (talk) 17:17, 18 October 2015 (UTC)
