Everyone wonders where the giant bugs of the carboniferous went. 'Extinct because oxygen, hurr' is the explanation for retards that eat the slop 'scientists' serve them.
The reality (((they))) don't want you to know is that they adapted to the changing oxygen levels by developing lungs. Limb pair reduction in arthropods is well documented, and so is segment fusion.
The carboniferous was full of giant arthropods. Permian, giant arthropods disappear, giant sauropsids and synapsids appear. OH GEE I WONDER WHAT HAPPENED! SURELY THE BUGS WENT EXTINCT AND THESE NEW ANIMALS DERIVED FROM AN AQUATIC ANIMAL NOT ADAPTED FOR LIFE ON LAND INSTEAD!

You type like a faggot.
Also that's just a paraphyletic clade then, which if you say that's reptiles then sure but then if you want to be actually and truly consistent then you'd need to include everything between.

(picrel is likely outdated/possibly wrong since I know turtles are taxonomic weirdos, but it helps illustrate the proposed grouping of reptiles here)
The difference w/ synapsids is that including all Diapsids as "reptiles" is way more consistent than including all amniotes, and you would need to include mammals as reptiles if you considered therapsids like dimetrodon to be a 'reptile'.

there are no reptiles at all. reptile is arbitrary, as arbitrary as calling spiders bugs. without vulgar english terminology confusing people, there is no scientific reason for such an arbitrary paraphyletic grouping to exist.

common names, scientific names, common groupings, and scientific groupings ought to be kept entirely separate. this basic policy decision would prevent all the whale-fish confusion among midwits like you.

Because the fossil record is biased and incomplete. Its like the first thing you learn in serious paleo, and it cant be emphasized enough. 99% of all fossil sites are either the result of riparian and lacrustine environments, volcanic or marine deposits because they are the only places where a dead animal can realistically fossilize and not end up getting eroded out of existence before we ever find them. Which means all we ever get are snapshots of generally a few million years of generally a floodplain or some marine environment where the conditions favored a sudden catastrophic burial of still living animals or the quick preservation of dead ones, we don't get to see highlands, deserts, forests, or whatever time appropriate equivalent there is to grasslands. We just get whatever lived near the floodplains or if were incredibly lucky in cases like the Messel pit a look into a tropical faunal assemblage because of something like a limnic eruption.

That's simply not true. The last common ancestor of things are only going to be found where entire families are known in detail. I can show you the last common ancestor of many Ceratopsids, for example, because the family tree of these dinosaurs is very nearly complete (with a few small gaps). The problem is that most creatures that people are looking for the last common ancestor for are pre-Mesozoic even so they're difficult to locate and belong to phylogenetic trees that are extremely incomplete.

Exactly my point. Even a hairless rat will never simply go dormant if put in a freezer. It will eventually get hypothermia, but that's different. A lizard in a freezer, yes even our precious "endothermic lizard" will almost immediately just freeze the fuck up and die. Because they're not actually endotherms and have basically no adaptations that come with BEING endotherms.

That's not correct. Here's an example. This (Chasmosaurus russelli) is the last common ancestor of Triceratops and Regaliceratops. These are two different tribes of Chasmosaurine Ceratopsids.

Where did the 'sci' part come from?

This is similar to the "Um actually no paleontologist believes this! It's just paleoartists" non-argument, which is 100% false too.

the weird science twitter account isn't an actual scientific source, retard. Actual cladists never said that humans could grow feathers, in fact, just the opposite, because the clade leading to humans and the clade leading to birds diverged something like 100 million years before feathers existed, (exact timing depends on whether Pterosaur pycnofibers are homologous to feathers or not, not sure if that's been resolved) so it should be impossible for humans to grow feathers unless some kind of genetic engineering was involved.
