Saturn’s atmosphere exhibits a banded pattern similar to Jupiter’s, but Saturn’s bands are much fainter and are much wider near the equator. The nomenclature used to describe these bands is the same as on Jupiter. Saturn’s finer cloud patterns were not observed until the flybys of the Voyager spacecraft during the 1980s. Since then, Earth-based telescopy has improved to the point where regular observations can be made. The composition of the clouds varies with depth and increasing pressure.
The winds on Saturn are the second fastest among the Solar System’s planets, after Neptune’s. Voyager data indicate peak easterly winds of 500 m/s (1,800 km/h).
Thermography has shown that Saturn’s south pole has a warm polar vortex, the only known example of such a phenomenon in the Solar System. Whereas temperatures on Saturn are normally −185 °C, temperatures on the vortex often reach as high as −122 °C, suspected to be the warmest spot on Saturn.

Savage 10 metre fish of the Silurian and Devonian Heavily armoured piscine torpedoes with fierce teeth roamed the oceans in the early days of fishes, in fact the Devonian era is called the age of fishes by palaeontologists as they had a huge burst of speciation and diversified to fill most marine ecological niches during this time. The now extinct (fortunately) class known as placodermi (plate skin in Greek) was the apex predator of these long gone waters, and thrived from 438 to 358 million years ago, dying out at the end Devonian mass extinction (one of the lesser ones).

I am so grateful that this thing is fucking extinct.
I would never have been able to tolerate having the job of creating this 3D model.
THIS IS WHAT MY WORST NIGHTMARE LOOKS LIKE.
I had a really stupid idea and had to paint it for a friend.
It makes me sad how no one ever seems to mention how wild the crocodilian-line archosaurs were. Dinosaurs get all the attention when there was equally crazy shit happening on the other branch of the archosaur tree.
There was a whole linage of bipedal crocodylomorphs during the Triassic that were basically identical to theropod dinosaurs, so much so that a lot of them were initially classified as dinosaurs!
Just fucking look at them!
And these weren’t just little lizard guys, there were some big lads running around.
Not to mention the long-legged ones that galloped around on all fours like some kind of terrifying reptilian dogs.
These crazy crocodiles aren’t just from the Triassic, either; there was a galloping, hoofed crocodilian that lived during the Eocene and likely hunted horses. (They were smaller and not quite as fast as modern horses, but still)
But don’t worry, they weren’t all meat-eaters! There were vegetarian and omnivore crocodylomorphs too! Just look at this guy!
He was an ankylosaur before ankylosaurs were cool (or even existed).
33,000 light years from the Earth, this globular cluster has an odd orbit around our galaxy, orbiting like a comet does around a star, and moving away as far as 100,000 light years from the centre.
It’s theorised that it’s likely a captured cluster, and appears to be undergoing core collapse, where the gravitational influence of the entire cluster bares down at the centre and causes black holes and dense stars to slowly migrate towards the centre, much as our own galaxy has the same mechanism creating the central black hole.
