I just started listening to the podcast True Crime XS based on a comment from u/One_Tomato_1521.

I am 23:11 minutes into episode one, published in 2020 and they are mentioning the maps that the TCBS just started to mention in the last season or two when they started collaborating with Somewhere in the Pines (RIP).

Were there mentions in previous seasons of the Maps and I missed it, or was this a massive oversight by the TCBS research team?

This is not an advert for the True Crime XS pod, like I said only 23 minutes in and im still getting a feel for the formating of it and the audio production isnt that much better than TCBS.

Abstract-

About 70% of North American large mammal species were lost at the end of the Pleistocene epoch [1]. The causes of this extinction--the role of humans versus that of climate--have been the focus of much controversy [1, 2, 3, 4, 5, 6]. Horses have figured centrally in that debate, because equid species dominated North American late Pleistocene faunas in terms of abundance, geographical distribution, and species variety, yet none survived into the Holocene epoch. The timing of these equid regional extinctions and accompanying evolutionary changes are poorly known. In an attempt to document better the decline and demise of two Alaskan Pleistocene equids, I selected a large number of fossils from the latest Pleistocene for radiocarbon dating. Here I show that horses underwent a rapid decline in body size before extinction, and I propose that the size decline and subsequent regional extinction at 12,500 radiocarbon years before present are best attributed to a coincident climatic/vegetational shift. The present data do not support human overkill [1] and several other proposed extinction causes [2, 3], and also show that large mammal species responded somewhat individualistically to climate changes [4, 5, 6] at the end of the Pleistocene.
