Did Mammal-Like Reptiles (protomammals) really had fur?


Hair/fur and mammals goes together like peanut butter and jelly. Its gives warmth to mammals in cold and temperate climates, and can be used for protecting the body (well except for fleas). But! Did Mammal-Like Reptiles the distant ancestors and predecessors of mammals had fur or hair? Finding early protohair is difficult. But did they had it? Sure dinosaurs have feathers no doubt about it. Or did Mammal-Like Reptiles had thick hides and scales. But they lasted until the early jurassic. Pretty impressive for primitive synapses since mammals already came into existence.

So did our old grandparents had hair

Yes. Fossils have been discovered with fur, or at least, imprints of fur.

A couple of interesting articles:

Getting to the Root of Fur ? Phenomena


https://virtevo.wordpress.com/2015/0...r-and-mammals/


Essentially the first hairs were 'feelers' and go a long way back.

From the 2nd article:

"The solution was to develop some sort of tactile apparatus—in this case it was vibrissae, or their more common name, whiskers. The ancient mammals crawled about their burrows using their long and rigid hairs to feel their surroundings. This theory is supported by the indentations in the therapsids’ skulls that are akin to those of modern whiskered mammals. The Thrinaxodon, for example, lived 250mya and had pitted foramina—which are tiny openings that nerves pass through—on its skull. This species was also covered in scales for the most part. (Keep in mind that although this is strong evidence, it is still not proof: there are a couple species of modern lizards that have similar indentations, but do not have whiskers.)"
