Or are the fossilized skeletons just a test?

I would doubt, raptors seem to be closer to archeopteryx than chickens. Also Synapsids are half reptile, I dont think they gave birth to young and they still had pointed tails, probably cold blooded as well.Birds are theropods. Chickens are actual dinosaurs.
The dinos kept mammals down for 200 million of years, and now we eat them out of a bucket. Synapsid Power !!!! Total Dino Death.
'Synapsid' refers in this context refers to the clade, of which all mammals, including ourselves evolved from.I would doubt, raptors seem to be closer to archeopteryx than chickens.

I know, Im referring to Cynodont which was one of them. The Carboniferous and some Triassic Synapsids are half reptile, they didnt give birth to young and they had pointed tails. From what I remember of Walking with Monsters, Cynodont was cold blooded.'Synapsid' refers in this context refers to the clade, of which all mammals, including ourselves evolved from.
"Half-reptile" is not the best way to characterize it. The traditional class "Reptilia" is more or less synonymous with the clade Sauropsida, while the term "reptile" is entirely frowned upon when referring to any member of the Synapsida clade, whether that member be a Therapsid or a more basal Synapsid; it was the norm for amniotes in the Carboniferous and the early Permian to possess scales and to be ectothermic, regardless of which of the two major clades that they belonged to. As for ectothermy in therapsids, it's still something of an open question as to when fully endothermic therapsids appeared but given the correlation between upright leg postures and endothermy, along with the morphological similarities between later non-mammalian cynodonts and "true" mammals, we can surmise that it is at least not outside the realm of possibility that cynodonts, or at least some of them, were true endotherms. It's also often suggested that some of the late Permian and Triassic Therapsids are "mesotherms", somewhere in-between warm and cold blooded.I know, Im referring to Cynodont which was one of them.

Most of my knowledge on the subject comes from when I was 8 and a prehistoric life nut so its good to know new info. And yes, Walking with is the best show(s) BBC put out besides Planet Earth with the full Kenneth Branagh narration. Except Walking with Cavemen, that shit sucks. Favourite show for a 6 year old in 2006 given that it was still airing on network television then. Also since Discovery and Animal Planet were the only things I watched from 6-12, Im gonna say Most Extreme, Prehistoric Park, Prehistoric Planet, Deadly 60 and Animal Face Off were the best shows on television then. Mutant Planet, Planet Earths I and II come close second."Half-reptile" is not the best way to characterize it.

That's my autistic post for the day. Also, the Walking With... series is fantastic, even if the science is a little dated in parts of them.
Shit man, you're reminding of how nice it was when there were tons of documentaries and general educational content on cable TV in the 2000s.Most of my knowledge on the subject comes from when I was 8 and a prehistoric life nut so its good to know new info.
