i got a great idea from someone on deviant art

walrus like Dicynodonts

Posted Image

and for the dracosuchids can we made them descend Dinosauromorphs (Lagerpetidae, Lagosuchus, Marasuchus, Saltopus, and Silesauridae) we can just remove true dinosaurs from the family tree

i don't see cold blooded animals takeing flight like crocs

I still love the aquatic dicynodont idea, it's an idea which always crops up with spec projects involving dicynodonts.

As for the dracosuchids, it's believed that crurotarsans were warm-blooded too, and that modern crocodylians are secondarily-cold blooded. I gotta be honest, I see them on the cruortarsan line than the avemetatarsalia line.

yes but while that live stayed near water or land the avemetatarsalia was heading for the sky

i see Crurotarsi more as water or near water animals staying on all fours(with a few exceptions)

they are like the mammal group and bat's are just lucky

Avemetatarsalia seems to me to be the only logical tract of where they should descend from

say hello to my friends Marasuchus and Lagosuchus

pardon the double post but here is another reason of why dracosuchids are more likely to fly from the Avemetatarsalia side of the family tree

Land, water and air

Archosaurs are mainly portrayed as land animals, but:

The phytosaurs and crocodilians dominated the rivers and swamps and even invaded the seas (e.g., the teleosaurs, Metriorhynchidae and Dyrosauridae). The Metriorhynchidae were rather dolphin-like, with paddle-like forelimbs, a tail fluke and smooth, unarmoured skins.
Two clades of ornithodirans, the pterosaurs and the birds, dominated the air after becoming adapted to a volant lifestyle.


the Pseudosuchia were heading for deep water while Avemetatarsalia was reaching for the skies just replace the birds with the dracosuchids only instead of coming from a true dinosaur like birds did it will come from Dinosauromorph

The dinosauromorphs only began to adapt towards flight during the Jurassic. In the Triassic, they were growing increasingly more grown-dwelling, starting out with small bipedal animals, which grew into the larger quadrupedal silesaurids and dinosaurs. And it was the dinosaurs that were able to evolve to fly.

The psuedosuchians weren't just adapted for water-living lifestyle, the rauisuchians, prestosuchians and sphenosuchians (my proposed ancestors for the dracosuchids) were clearly adapted for a terrestrial lifestyle, but went extinct when the dinosaurs took over. But since there is no dinosaurs, they're free to continue dominating the earth, and move into new niches. Just like how some dinosaurs evolved to be capable of flight, I'd say some pseudosuchians could do the same.

so they walked the land big deal

we walk on land and i don't see wings sprouting out of our shoulders

pterosaurs are part of the same line that led to dinosaurs and they soared even before dinosaurs

even being a biped did not mean that they are going to fly

and besides most of the animals that now fly lived in trees and i don't see any tree crocs

Non-dinosaurian dinosaurormorphs walked on land and I don't see them with wings either. Guess that means they're ruled out from flying too.

Bats are part of the same line that leads to humans and flew long before we showed up. Does that mean we're destined to develop wings and fly too?

I never said that being bipedal = flight.

Because they never got the opportunity. Dinosaurs forced the pseudosuchians into other unoccupied niches, which allowed them to take advantage of the trees and develop an arboreal lifestyle, and eventually flight.


Just because the pseudosuchians didn't evolve flight in our world, doesn't mean that they couldn't. Crocodylians have been shown to be extremely diverse, even in the time of the dinosaurs. There were not only the aquatic crocodilians that exist now, there were the fully marine types as you previously mentioned, there were also large, fast-running terrestrial crocs that could chase down dinosaurs, small, heavily armoured herbivorous crocs, ones with a wide flat snout like a duck's, giant filter-feeding crocs and cheeked pig-snouted/trunked crocs. There's such a huge variety of crocodylomorphs, and imagining them being able to evolve flight hardly seems like a stretch.

Besides, dinosauromorphs were not adapting towards flight. Flight in dinosaurs was pretty much a happy accident, feathers didn't evolve for flight, and pennaceous feathers were used for display. The fact that pennaceous feathers on the arm (forming a wing) made them capable of flight was a total fluke. A fluke that they took advantage of, and became one of the most successful animal groups ever. But since dinosaurs didn't evolve, feathers (as we know them) wouldn't have evolved and the dinosauromorphs wouldn't adapt for flight.


Without the dinosaurs, the pseudosuchians could continue to diversify throughout the Mesozoic unimpeded, leaving the door for flight wide open. The dinosauromorphs would not be able to become the dominant lineage, and would most likely remain in their current niches. None of which had any adaptations towards flight whatsoever.

very well you win

but will the dinosaurmorphs still exist? they too was kicked into extinction by true dinosaurs

and with the feathers idea

some paleo artist thought that since crocs were warmblooded then maybe they had feathers and that it was a hidden trait in archosaurs in the first place.

but unlike a peacock-croc it was more like fur

ok

then i have loads ideas

but don't worry they will basically look more like small theropods and maybe small heterodontosaurs and Hypsilophodonts

They will have the niches but not be true dinos i promise you not see hadrosaurs, ceratopsians, or sauropods from me

then again i see silosaurs doing some sauropod mimicry
