Globes of Earth during six eras (commission) -- Part 2

[Chick]

Last fall, Lingon posted about a commission he (and I) got for some globes representing Earth through geological history.

Lingon completed his quicker than I did, and posted them here: http://www.cartographersguild.com/sh...ad.php?t=31549

I finished mine later in the fall, but I'm finally ready to show them.

These were a commission from Richard Garriott to paint physical 6" wooden globes to display with his fossil collection, showing the Earth as it was in earlier geological eras.

I chose a slightly different set of time periods, going further back than Lingon did, so the dates of the globes are different than his.


The times I chose were

Vaalbara 3.5 Billion years ago, land was formed but no oceans yet, lots of huge volcanoes (think Olympus Mons), life just starting in the warm shallow waters beginning to accumulate.

Columbia 2 Billion years ago, a time of global cold, sometimes called the "snowball Earth", tectonics well underway so lots of mountains and oceans, with only single-celled life in the oceans.

Rodinia 1 Billion years ago, landmasses fragmenting and separating, still only single-celled life in the oceans

Pannotia 500 Million years ago, continents separating and colliding, land and ocean similar to today, with life spreading to the land, mostly in the form of algae and primitive plants.

Pangaea 250 Million years ago, warm and humid, rich terrestrial and marine life, including reptiles, birds, and dinosaurs on land, fish and shelled animals in the seas.

Modern 0 years ago, cool and rich with life.

I'm hoping Richard will send me a photo of the globes standing in his geological collection.

I'd also like to give some credits:

To Malicious-Monkey for posting some ideas here: http://www.cartographersguild.com/sh...ad.php?t=30877
This thread was posted only about a month after I took this commission, and it was a godsend for ideas about how to proceed. Then she also sent me a fabulous set of advice and ideas via email, which I went back to time after time when I got stuck on how to do something. I can't thank her enough for all that help!!

To Professor Pat Bickford (Syracuse University) for all of his original teaching when I was a grad student there, and for some fantastic advice and visualization of what Earth looked like in the earliest eras when I contacted him during this project.

To Gillis Bjork (Lingon) and my friend Brett Sanford for their advice on how to do some of the physical preparation and painting of the wooden globes.

It's looking cool Chick! I really enjoy globes and keep in mind to do some in the future.
