Trilobite Court, Diabase Square, Fluvial Terrace and Other Street Names

Trilobite Court, Diabase Square, Fluvial Terrace and Other Street Names

I was Googling “trilobite” yesterday. By some weird logic, I was sent to Aldie / Stone Ridge,
Virginia (20105). There I found streets that are named “Fluvial Terrace,” “Trilobite Court,”
“Diabase Square,” “Apatite Square,” “Quartzite Terrace,” “Feldspar Place,” “Greenstone
Drive,” and “Devonian Drive,” among other street and court names that include geological terms.

I found a “Trilobite Trail” in Fort Worth, Texas; a “Trilobite Trail” outside of Jemez Springs, New
Mexico; and a “Trilobite Trail” outside of Ignacio, Colorado.

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.
