- Comments
- Pashley: When originally reported, the fossils from this site could be given only a minimum age of 8000 BP based on geological evidence, and the Pashley Pit horse bones were consider to represent "the youngest indigenous fossil horse known in North America" (Churcher and Stalker, 1970: 1020). The development of accelerator mass spectrometry dating has opened up new opportunities to determine the ages of such fossils (Hills and Harington, 2003), in this case nearly 3000 years older than supposed.
