So… it swims like a fish…

Right?! I was expecting a quite different swimming motion. This was a rather useless animation.

I'm far more curious about the scale of this shark. We talking a trout the size of a shark or a shark the size of a trout?!

It’s a shark for ants, and other bugs that can’t swim good.

Thanks I wasn’t sure if the fish swam like a fish or like a donkey

lexi_con t1_ir6m4oh wrote

This animation is based on the discovery of thousands of fragments like this, so it could very well have been a donkey for all they know.

Take my advice and stay out of the lake. It's the slaughterfish. They'll swarm you.

Swarms of slaughterfish in the lake? Forget that! I'll retreat to the highest mountains just to stay as far away from that mess as I can.

takes notes on fish movement now this is a fish and it…checks notes…swims in water? Is this bitey or licky?

Fanjingshania is the earliest jawed fish known, at 439 million years old of the lower Silurian, and could be to be a member of the group which placoderms (and all other jawed fish) emerged from.

However, we believe placoderms and all other fish (the ancestral group which would later become cartilaginous fish, acanthodians ("spiny sharks"), and bony fish, had already diverged at this point, and likely did so during the Ordovician.

There is an outside possibility that Fanjingshania is a member of that basal population, from which all other fish groups came (and, therefore, all vertebrates) but this is looking unlikely, as it's too late and already carries features giving it affinity with the acanthodians, which have no living relatives.

A 2016 study found all cartilaginous fish to be more closely related to acanthodians than any other group and recovered acanthodians as stem-chondrichthyes, while another group in 2012 had found acanthodians to not actually exist and assigned all its members either to Chondrichthyes (cartilaginous fish) or to bony fish.

Most taxonomists at the moment seem to be agreeing with the acanthodians as stem-chondrichthyes model.

Additionally, working out how these swam was very important because these had the earliest pelvic fins. Vertebrate legs emerged from pelvic fins. It can give clues into the later evolution of tetrapods.

TL;DR; This is probably a member of an early divergence from the lineage which resulted in vertebrates, not an ancestor of vertebrates itself.

Thank you. Was looking for a comment like this. Finding out or even speculating modern animals’ ancestries are always fascinating.

No no it’s really interesting: They are showing us it actually swam like any fish does.

The animation is not very exciting, but the discovery of this fish is. Broadly speaking, fish fall into two groups: jawless fish (only a small number of living species, including the lamprey, but once the only type of fish), and the jawed fish, which includes the vast majority of the fish. The jawed fish can also be divided into two groups: the bony fish, which is the majority of fish, including our own ancestors, and the cartilaginous fish, which are sharks, rays, skates and chimaeras. This creature has just been found, and is a very old member of the cartilaginous fish, so related to modern sharks, and is the oldest known jawed fish, as they say it lived 420 million years ago.

I mean, they can't be completely certain. There's so many other ways for it to swim. /s

TikkiTakiTomtom t1_ir7e8oz wrote

People make jokes but there’s different swimming strategies employed by fish and other marine animals dependent on their anatomy (big dorsal fin etc)

For example:

  • whales and dolphins swallow the water in front of them and the force of it pulls them forward
  • starfish require the symbiotic assistance of teenage mutant ninja sea turtles to throw them like throwing stars
  • speaking of which certain species of sharks discovered in the 90’s traverse are highly complex and sophisticated, traversing only via bikes and roller skates
  • polar bears propel themselves like squid using their farts but because they just float atop the water they’re more like the Portuguese man of war which also fires off a brigade of farts
