Online Lecture About The Formation of Terrestrial Planets

Online Lecture About The Formation of Terrestrial Planets

While slumming on Youtube, I came across a really nice lecture on the formation of terrestrial planets. It is: The Formation of Terrestrial Planets - the 2nd Lobanov-Rostovsky Lecture in Planetary Geology Published on Oct 8, 2016
https://www.youtube.com/watch?v=fMj9whiI31I

Fortunately, the audio is increased just before the main lecture begins. Only the introduction is hard to hear.

Online Lecture About Late Pleistocene Megafaunal Extinctions

Online Lecture About Late Pleistocene Megafaunal Extinctions

There is a 2012 Tyrrell Museum Speaker Series lecture
about terminal Pleistocene extinctions on Youtube. It is:

Gary Hanes, Late Pleistocene megafaunal
extinctions and the unsettled timing of the first
human dispersals into North America. Royal
Tyrrell Museum Speaker Series 2015

Gray Hanes mentions briefly the use of Sporormiella
spp. microfossils to estimate the age of megafauna
extinctions in his lecture. How this is done is discussed in:

Gill, J. L., J. W. Williams, S. T. Jackson, K. Lininger,
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.

The Royal Tyrrell Museum also has a really nice
online lecture about meteorites. It is;
