Sea scorpions thrived for 200 million years, coming in a wide variety of shapes and sizes. Over time, they developed a number of adaptations--from crushing claws to flattened tails for swimming. And some of them adapted by getting so big that they still hold the record as the largest arthropods of all time.

@daniellemurphy9755 5 жыл бұрын

Geologists usually define geologic time blocks (pick whichever unit you want to use) by large die-offs/extinction events or sometimes planet-wide changes in conditions like atmospheric O2/co2 content or temperature... MOST IMPORTANT: 1. The disappearance of huge amounts life across an immense swath of species, genera or even families from the fossil record and/OR 2. the appearance of new life en masse (especially with few to no transition forms before the disappearance of the other lifeforms) or the vast expansion in numbers and diversity (and usually size depending on the amount of 02 available for animals) of a pre-existing but previously marginalized or geographically limited species/genus/family. This tended to lead to the wholesale extinction of competitors, e.g. the devonian/age of fishes The species not killed off by an extinction event filled the empty niches left by the dearly or not so dearly departed creatures which allowed the leftovers to diversify, specialize and sometimes get bigger (not necessarily to gigantic proportions, but sometimes - depending the circumstances of a given event). Finding indicators of what caused the extinction event, like unbelievably huge deposits of basalt or glacial til/scarps/valleys or a globe encompassing continuous layer of iridium and burnt material/ash or tectonic activity like extensive orogeny or continent break-ups that coincide with the disappearance of life, is just a huge bonus.

So if that's how chelicerates left the water, how did the insects, diplopods, chilopods, and isopods first leave it? Did they all diverge in the sea or did some have a common terrestrial/aquatic ancestor

@cyberpotato63 5 жыл бұрын

They had a common aquatic ancestor. Some of the divergence happens in water and some on land. Think of it this way, an ongoing evolutionary tree diverging in water. Along the way, several species become adapted to land. This happens only a few times spread out over tens of millions of years. The species that become land adapted also evolve and diverge branching out into many different groups. All along the aquatic groups continue diverging. To complicate things some species of land animals become aquatic and start diverging into further aquatic species. Along the way extinction pears back the tree of life, and occasionally it wipes out much of life.

The American pronunciation is quite funny. Would be interested to know if the word has been adopted long ago enough that the wrong way to say it has become the right one yet.

@aecides3203 3 жыл бұрын

Quite often when hearing about ancient sea life I imagine how amazing it would be to pop back in time, go for a swim and watch them. In the case of Jaekelopterus I'm pretty content looking at fossils - at least a Mossasaur or similar would be a case of one chomp and that's that, being grabbed by giant claws and torn into bite size chunks is not the way I'd like to go.

I do have a video suggestion for you. I always have been curious about tasting dinosaur meat, asking myself how much it would taste like chicken or crocodile. I also remember seeing a dinosaur "mummy" with so well preserved muscles that they were almost looking good to eat and ready to carve. The fact that it was turned into stone made the meat looks like it was cooked. Now seeing the bits and pieces of claws in that video made me feel hungry for lobster claws, but I realized that those would probably taste more like scorpion than lobster. My video suggestion would be to make a selection of extinct animals with close modern and alive relatives that we can eat today to get an idea of the tastes from the past. I would also be nice to have edible plants too, so we could figure what the Flinstone gastronomy could taste like (even if this would have been impossible for human ever taste those ingredients because they never lived at the same time) I also feel it would bring a new reference for feeling the past. We always talk of color, texture, lenght, weight, but we never talk about taste. Of course, this might be totally off, but it would be a start to dream about...
