Pterosauria

(Obviously the best Mesozoic winged vertebrates.)

Speculative Evolution Concept: Ankha (Numenodraco lupofaciem)

kenbrasai:

Reaching a wingspan of 10 meters, the Ankha (also known as Sky Tyrant, Emperor Dragon/Wyvern or Baiheitianlung) is the largest volant non-pterodactyloid pterosaur ever known, and easily one of the largest flying vertebrates to have ever existed. At such a size, and being a specialised, migratory or nomadic soarer to boot, geographical barriers mean very little to it, and it can in fact be found all across the world’s landmasses, though only occuring rarely or even being completely absent from some remote islands. The Ankha is obviously present in most terrestrial habitats, but preffers open spaces like grasslands, or alpine environments.


The Ankha is a massive campylognathoidid* pterosaur, magnitudes of size larger than its closest known relatives and indeed all living flying vertebrates. It bears a thick black dorsal and facial pelage, a peach underside (throat and torso) and eye patches, grey wing membrane uppersides with white dots that become more common dystally (in some individual, the wingtip uppersides are entirely white), orange/gold wing membrane undersides and red tail vanes. It possesses a pair of “ears” or “horns” made from bristle-like pycnofibers - similar to the “ears” of eagle owls, albeit wider and attached right above the eyes -, but otherwise it possesses no extravagant head ornament. Its snout is covered by pycnofibers, some of which specialised as large vibrissae, which combined with the “raptor” like snape of the jaws, gives it as a distinctively canine-esque appearence.

The azhdarchid survivor of the K-T extinction event, and the common ancestor of the neoazhdarchids, pictured here next to the corpse of its larger relatives of the skies. It and creatures like it live on islands throughout the Americas and Europe. It has limited aquatic abilities and is omnivorous. It is a hardy survivor with limited nutritional needs. It would spread and give rise to the dominant megafauna of the cenozoic. This K-T extinction event killed different species than in OTL. Why some species survived OTL and others didn’t may have just come down to blind luck. The enantiornithines survived in greater numbers than their neoornithine cousins. Due to their restricted flight ability though, they would be outcompeted in the sky and become a vital part of the Cenozoic terrestrial fauna, diversifying just as the neoazhdarchids didMammals were hit harder than in OTL and, while still there, would not play as big of a role as in our world. They would still be relegated to burrows as archosaurs—birds, pterosaurs, and crocodylians, once more dominated the earth.

Pteradactylus , the cause of people calling all pterosaurs Pterodactyls. Super cute and super small and fuzzy.

Some sort of sabre-tooth, scythe-clawed neoazhdarchid from an alternate pleistocene. It gets around by bounding and galloping after its prey before leaping and clinging onto them with its scythe claws and sharp incisors. Packs can take down prey many times their size.
