>>2370374
Is that the actually same specis though?

I don't think so.

>>2370380
I'm not sure about the pic, there are like two species, but Coelacanth as a whole is considered a living fossil because it has changed so remarkably little in 400 million years. How it happen is that 400 million years ago this dorky fish found a niche environment with virtually no predidation. And it just stayed there with no real need to evolve relative to everything around it.

Are there any known species of jellyfish that haven't undergone any sort of evolution since the Pre-Cambrian?

>>2370393
Actually, there's no evidence of the current species of coelacanth (Latimeria chalumnae) being earlier than late Pleistocene

>>2370379
Nautilus pompilius is actually pretty ancient (late Eocene), but not the same species as the Cambrian one

No there isn't. Sadly, jellyfishes aren't common in the fosil record because no hard tissues.

>>2370578
Meh, google told me 400mil years ago. Enlighten me if you care to.

>>2370776
Coelacanths as an order appeared 400 mya. Early species include Miguashaia bureai, Allenypterus montanus and Rhabdoderma elegans.
Modern coelacanths (genus Latimeria) appeared very recently in the fossil record.

Does anyone else have this weird feeling when looking at these ancient species? They feel out-of-place to the current time, when in fact they're the original inhabitants of our planet and we're the newcomers.

Anyway, here's some cycads. A species of tree that survived the Great Flood of Noah that wiped out the dinosaurs.

Really? There was a ginko tree near my house in the south when I was a kid. I wonder if it's still there

that triggered me

>>2370978
Early Eocene, it's actually pretty old.
>>2370980
Nice try, but the genus Gunflintia went extinct in the Cambrian.

Are you Chinese?

I hope that was a bait post

>>2371041
they are really common as ornamental trees, I have one in my garden too

>>2369916
That tree is actually Handroanthus chrysanthus

Lingula Reevii is a brachiopod from the early Ordovician, possibly Cambrian. Only recorded in a few isolated pockets of reef.

>>2371154
Ahh, the original living fossil. Also, the basalmost species within the genus Lingula. I wonder how old the species L. reevii actually is, with a little luck, someone may be able to find this guy on Palaeozoic strata.

>>2368894
I had these niggers in a kit as a kid and they swam around in a tray for a few weeks after coming from dried eggs

>>2371315
That's what made then so successful. Their eggs stay alive under very harsh conditions for quite awhile.

>I had these qts too.

I highly doubt any living specimen from today would be able to successfully reproduce with one of the supposed same "species" from hundreds of millions of years ago.

>>2371385
Of course, DNA changes even when appearance does not. When people refer to an old species or a "living fossil" they are talking about a lack of macro changes. The organism stayed in pretty much the same shape, structure, and niche over hundreds of millions of years.

Can't we genetically engineer them to live for like a year or two? They'd be the ideal low-maintenance aquarium pet if they didn't die after a week.

>>2370980
can you put them in a bun and eat them?

>>2373536
Cool, according to the insect encyclopaedia, this guy dates from late Cretaceous

>>2370980
Would it be possible to keep one as a pet in an aquarium? It's like a pet rock but actually alive.

>>2373569
Mine lived about 50 days.

>>2373928
No. It takes hundreds of thousands to millions of years to culture a stromatolite, in the wild environment with waves and weather pressure creating plenty of opportunity for sediment to aggregate over time. If you want "living rock" I'd look toward culturing endoliths instead.
