Ichthyosaurus acutirostris with ammonites, Harpoceras falcifer
The pyritised ammonites really make these piece epic!
reblogging to show how massive ammonites really were and, how radiocarbon dating works, since I think it’s related:
see, that primitive dolphin wasn’t any kind of mammal, it was a reptile, not even a dinosaur. It died and fell into the mud, then got covered in more mud before anything ate it… and then, it sat there, minerals seeped into the parts where its flesh and bones were and depending on which minerals managed to seep in, ended up turning into rock. The process is so slow, and so gradual, that very fine and often microscopic details can be seen in what just looks like a big sheet of stone.
When we live, we eat food and drink water that has gone through the various cycles on our planet, and we’re all made out of carbon-14 and carbon-12. This carbon-14 is a special type of carbon that’s made by cosmic radiation hitting our upper atmosphere and it rains down upon us and replenished in us as we age and live by breathing and eating. But when we die, we stop taking in that carbon and all the carbon that was in us as we died sits there… and decays. A lot of it gets eaten, sure, but some of it stays behind to get fossilized.
Thousands or millions of years later, scientists can measure exactly how long that carbon in the fossilized creature was sitting, and how long it was not taking in more carbon(read, dead), and so measure how long it has BEEN dead, by how decayed the carbon is. It decays just like clockwork, and this process of measurement is called radiocarbon dating.
That ichthyosaur is millions of years old, and we know this because of the amount of decay the carbon it was made of, has had. It’s infallible as much as atoms and radioactivity are. So, yes, the earth, and at least this animal, are older than the biblical 6000 years by far, the carbon in it says so. To deny it is to say that radiation and atoms itself don’t exist and don’t function, which is… sorta, well, uneducated imho.
