250 years of human history in 3 minutes, a sort of trailer for the educational portal Anthropocene.

Just been clearing up some old hard drives and found this.
It’s pretty interesting and shows really well how, even in a relatively small area, the geology of Scotland is extremely diverse!
Can see those nice terrane boundaries pretty clearly on this map, and it’s nice and neat

Only 2 days until all exams done :)
Just need to get through today and tomorrow with revising two subjects that are completely opposite to each other - micropalaeontology and tectonic geomorphology.
I seriously think Earth Sciences has to be one of the harder degrees because of the all the stuff we have to learn.
AND if we don’t learn it properly and go in to jobs and fuck up, it’s a big deal.
Nummulites, and why you should be impressed.
These creatures are basically the giants of the microfossil world. They are foraminifera, and are protozoans (single celled organism). What you see in the photos are the tests (solid insides made of low-Mg calcite) and they would have been surrounded by a slimy cytoplasm so they would have been a lot bigger!
Nummulitic limestone is what the pyramids in Egypt are made from, and they are a big deal in terms of correlating rocks in the Eocene of the Mediterranean.
What is astonishing about them is that they are single-celled organisms, but grow to a massive size! There are still debates about why, but it is believed that they had algae symbionts (diatoms) which helped boost the nummulites’ metabolism so they could grow bigger and live longer!
