Today I am grateful for;

Above zero temperatures, enough that there is some standing water.

I got some much needed cleaning in the bathroom, mainly the floor. The floor in that room is always dirty, probably because I always have hay and hair all over me. So much of it is hard to clean well, like the area under the tub, and under the cupboard with the sink. There is a maze of pipes between the two fixtures that is hard to clean. Then an awkward space between the sink and the exterior wall. Most of the time I do a quick sweep, but not thorough. Today I took everything off of the floor and out from underneath everything and cleaned it.

I went to see River, and he was kind of sleepy. Maybe because it is so nice and warm. We did well with our work, he stayed with me better on the draws today. I didn't push him hard because his breathing seemed a little off.

There was a person having a lesson that was there for part of my ride, so that was nice.

Today I learned about an extinct group of creatures called Eurypterids. They died out 467.3 million years ago. They were kind of like horseshoe crabs with long tails, some people call them sea scorpions, but they did not sting. What is impressive, is that one species could reach sizes of about 8 feet long (lots of other kinds were small). Imagine an eight foot long lobster-ish creature!

Personally, I shudder at all the enormous, terrifying things that used to be alive. The giant horrific fish, giant tigers, giant bears, giant wolves, way bigger sharks. What is it with all the huge shit that used to be alive?

The only thing that might have been positive, is maybe this one huge kind of Eurypterid was tasty. I am a vegetarian, but maybe catching a three hundred pound lobster would be awesome for your tribe (not that there were any people back then, but if Eurypterids had not become extinct).

gigantism is thought to have occurred, especially in marine environments, primarily due to high primary productivity (food) and oxygen availability. Over time, as resource availability changed and became generally more depleted overall, smaller forms become more evolutionarily favorable.

There's a good book by Stephen Gould called Wonderful Life that goes into this a bit if it interests you, specifically in relation to the Canadian Burgess Shale.
