Hunting Fossil Vertebrates in the Eastern US, Alberta, and the Atlantic Ocean

Hunting Fossil Vertebrates in the Eastern US, Alberta, and the Atlantic Ocean

The Royal Tyrrell Museum has A couple of lectures about fossil hunting available online.

One is about hunting dinosaurs in the "Dinosaur Alley" of the northeastern United States is:

Paleontological Notes from the Urban Jungle: Or... Conducting Field Paleontology in spite of Sprawling
Holocene Overburden that is the Baltimore- Washington-Philidelphia "Megalopolis" by Thomas Lipka, Royal Tyrrell Museum Speaker Series 2013
https://www.youtube.com/watch?v=gg3mIRf-Fqo

Another is about hunting vertebrate fossils in Alberta is:

To Hay River and Back: Fieldwork on a 370-Million- Year-Old Beach in the Northwest Territories by Donald Henderson and Chris Capobianco, Royal Tyrrell Museum Speaker Series 2014
https://www.youtube.com/watch?v=ZvdTLYFGLi4

Finally, a quite well done and very fascinating lecture about looking for Albertan dinosaurs is:

Dinosaurs in the Deep: The Sinking of the SS Mount Temple by Darren Tanke, Dinosaurs in the Deep:
The 1916 Sinking of the SS Mount Temple and her Albertan Dinosaur Cargo. Royal Tyrrell Museum
Speaker Series 2013
https://www.youtube.com/watch?v=8XTFNTDK7W8

Related web pages are:

Dinosaurs in the Deep
http://www.ssmounttemple.com
http://www.ssmounttemple.com/ssmth3.htm

It would be fun if someone could find the money to find the Mount Temple and possibly salvage the
dinosaur fossils that were sunk with her.
