[meteorite-list] Lecture on Meteorites -Royal Tyrrell Museum

[Paul H.]

The Royal Tyrrell Museum has some really nice
lecturs online. One of them about meteorites is:

of Possible Seeds of Life. Royal Tyrrell Museum

Also, a 2012 lecture about terminal Pleistocene
extinctions is

extinctions and the unsettled timing of the first 
human dispersals into North America. Royal 
Tyrrell Museum Speaker Series 2015

Gray Haynes mentions briefly the use of fossils 
of Sporormiella spp. to estimate the ages of 
meagfauna extinctions in his lecture. How this is
done is discussed in:

and G. S. Robinson, 2009, Pleistocene megafaunal 
collapse preceded novel plant communities and enhanced 
fire regimes," Science, vol.326, pp. 1100-1103.

Gill et al. (2009) found that " Megafaunal populations 
collapsed from 14,800 to 13,700 years ago, well before 
the final extinctions and during the Bolling-Allerod 
warm period.
