they had popcorn a gabillion years ago? what’s old is new again. small world
In other news, water is wet.
Duh...you have to be a scientist to discover such amazing facts?
Do they have fossil theaters with fossilized sticky floors nearby?
I learned this in college back in the 60’s. Loved them Globergerina thingies. And Graptolites were cool - looked like microscopic saw blades.
My work as a Student Assistant was to find Conodonts (looked like cusp teeth, either a single tooth cusp or multi-teeth on one basal cusp),in limestone sludge (acetic acid does wanders to limestone rocks).
Each environment produced a different colored species of conodont. If I remember correctly, the Upper Cincinatti Formation produced beautiful amber colored Conodonts, while the Chambersburg, Pa. Ordovician produced all asphalt black species except for one pure crystalline one I found amongst them.
In the world of geology and paleontology, you are want you eat or swim in.
Some comments on your charts. Note the sharp drop around 34 million years ago at the beginning of the Oligocene. That was caused by among others the Chesapeake Meteor strike, about 60+ miles in diameter running from Norfolk up into the Delmarva Peninsula. Popogai (sp?) crater in Russia also about the same age and size, and the nine mile diameter crater of that age off Toms River, NJ. Regarding the sudden shift about 3 million years ago, I believe that is when North and South America were joined, thus disrupting ocean currents, and also leading northern species to move south and kill of some major species there. Does anyone have a clue about the shift from the 41 kyr cycle to the 100 kyr cycle?
Can't speak for other parts of the country, but here in Pennsylvania, our climate changes significantly almost every day.
For example, just today it will change by 25 degrees!
Yes, from 55 degrees F to 80!
And tomorrow the same.
And you say all this climate warming is caused by SUVs and coal?
Isn't that amazing...
