A brave new world: the dinosaurs not quite wiped out.....

Thanks! I hope you enjoy the rest of this TL! Did you enjoy me " walking with Dinosaur" style narration?

Yeah I love that series when you were narrating all I could think of was the episode from walking with beasts where the horses are being hunted by te terror bird

Funnily enough i was thinking the same thing- notice how there are similar creatures in the TL....
 
I think than the Dromaeosauridae of the late Cretaceous cannot only evolve in predator like gastornis.

The ecological niche is empty in the early paleocene and they can evolve also in vegetarian animal. Primary a part of them evolve in an omnivore alimentation a secondly in a completly herbivore alimentation and they become like the Therizinosaur.

If they occur in the Mezozoic with big herbivores they can also take place in the early Cenozoic with any big herbivores.

Also they can evolve in arboreal lifestyle because thez have hands and unlike the Mezozoic there were primate in the Cenozoic.

True- but you forget that Troodon was actually an omnivore- not just a carnivore! I think it could adapt.
 
sole survival of even a single additional species which would later flourish would cause massive butterflies. Its almost certain there wouldnt be any recognisable animals from our timeline.. no peryssodactyls, no gastornis.. no leptictidium.. altrough forms similar to them would surely appear

Well one guy on deviantart had a project in which few species of dinosaurs (few maniraptor species)
trodoon descendants were the most succesfull ones, evolving into wide range of herbivores and gave rise to an inteligent species as well as beaked carnivores

the sole survival of maniraptors without doubts caused massive butterflies so altrough various groups of mammals had already early representatives in early cenozoic/late cretaceous, nothing known from our earth evolved

some pantodonts gave rise to tapir-like and bear-like animals

Europe- though the timeline will be based all over the world. The situation will be the same in North America.

That totally butterflies away humans then. One could argue for a butterfly net over Gwandonaland (Australia, Antarctica and S. America), but not Europe.

Ledalek - Awesome pictures, but would that species have the manual dexterity necessary to make those kinds of tools?

Hmm, I agree with carefulness here. Much of the big changes that allowed primates and later hominids to evolve had to do with climate change, but still... successful species such as the the troodon decndants will have, and as Archon already took into consideration, have an impact on how mammals evolve. Of course we don't know if humans will evolve in this TL at all.

Very good points! But did you notice some things?
Firstly: The horse- like animals who names I've already forgotten were changed: they had longer legs and bigger ears. And notice how there's no terror birds.......
Secondly- climate is still the same and why would troodon descendants stop some hominids from going Bipedal- in fact, this process may be speeded up as the Australopithecus needs to escape from predators!
And by the way- your pictures are Awsome- in fact many of your pictures reflect what i was thinking and what creatures will evolve! But..... Troodon is the only survivor and will not be going Herbivore! Think about it...... meat creates bigger brains and predictors need to create hunting strategies to get food- hence why Dogs or lions are smarter then cows- who just need to evolve the right stomachs to consume grass- not demanding on the brain is it?

The mammals will evolve differently- that much is certain- but the smiler creatures will still develop to adapt to the same climate OTL. Thanks for your points!

P.S why is that bird thing holding a spear in it's mouth? how could it create a spear in the first place? A few issues there methinks....
 
I don't like the fact that the dinosaurs use their weapons through their mouths

Troadon most Lilly could develop basic tools using it's hands yet may face te neanderthal problem of trying to upgrade them because of their hands

Also I doubt they would use cloths as they have feathers

That problem my Agilodon will be adapting to in my next post.....
 
Dromaeosaurids cant evolve into tool users IMO, why would they need tools, they already have effective tools for killing their prey. I hardly see dinosaurs as becoming sapient, however i won't say that it's impossible, but even if, they still have their typical theropod bodyshape like the picture shows, and not become humanoid like older reconstructions suggest. Our ancestors had to make tools so that they can easier hunt their prey. Humans or alteast something similar could potentally evolve. Our ancestors wer monkeys, monkey like animals could also evolve with dinosaurs being alive. Mammal were quite diverse in the Cretaceous, some even preyed on young dinosaurs. I doubt dinosaurs would fill the niches normally monkeys would fit. primitive primates might existed during the late Cretaceous aswell. so they are in the realm of possibility. wheater they would be able to be sapient like we are, is also possible, however rather unlikely.
