Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

what if the bolid that hited earth during credacerous will be 12000 meters

the extinct spicies are
-all hemichorodates
-all flower plants(with few exceptions)
-all dinosaurs (with exception of bambiraptor)
-all pterosaurs
-all tailless amphibians
-all rays
-all rays
-all mamals (with exceptions of gondwanatheria,marsupials and eutheria)
-all squamates(with few exceptions)
-all birds (with exceptions of ichtiornis)
-all arachnids(with exceptions of scorpions and spiders)
-all crocodiles

sow wath you think (we speculkate about life on earth 200 milions after this K-T)

First off the asteroid was predicted to be 10-15 KM. So 12 KM won't be that bad.

Why kill of hemichordates? They never grew big, they won't influence anything.
Why kill flowering plants? They're more successful than conifers because they can spread faster.
Why only the Bambiraptor survive?
You don't want pterosaurs, yet you're also killing birds. So what will fly?
By tailed amphibians, do you mean just salamanders or salamanders and caecillians?
What did rays ever do to you?
So basically you are just killing allotheres and all non-marsupial metatherians.
No comment on squamates.
Again, what will fly?
Why would all non scorpion and spider arachnids die? Most of them are microscopic, so unless there was an extinction bigger than the Permian extinction they won't die.
Crocodiles had a chance of dying, so that's not implausible.

What would make this alien? And you are asking what will it be like with this extinction in 135 million years future. And again, what will make them look alien? It's not like tripod or hexapod chordates are going to spring into existence.

i have an error in extiction list the tailless amphibians will die out

alien because the animals will be extremly difrent there will be serpentoid mamals,
tripod descendands of ichtiornis, balon brown algae will take the niche after flower plants the starfishes will go onto land, etc

Okay, okay, okay, what????????

There are numerous problems with that. First off, serpentoid mammals cannot exist, our rib structure won't allow it.

Why would ichthyornis develop tripodness? What would actually happen is that they would retake all flying niches until another flyer evolves. Also, new legs can't appear out of nowhere, especially on chordates. Chordates just can't get new limbs.

Conifers will take over the land before algae does. There are so many ways conifers are better than algae. The best that brown algae can hope for on land is a fungus-like niche, but first it needs so much adaptions before it can even go on land.

Starfish cannot go on land. They simply cannot. Their water vasculatory system restricts them to the water. Land squid will evolve before land echinoderms (no land squid though, those things are just wrong).

in the ichtiornis tripod the wings will change into new legs and tail with back legs will develope into one leg.

the serpentoid mamal will be only legless creature

i am saying abut an algae that looks like leafes of grass

the starfishes will develope into new group when going on land, but they need to be in wery wet enviroment

Or it will overtake flying niches and some develop flightlessness like birds usually do. Icthyornis tails were incredible small and in no time in history did legs fuse to tails or legs fuse at all. They were only lost.

Again, serpentoid mammals cannot exist. Their structure is totally different from reptiles, they cannot lost legs.

Conifers would just grow smaller as they did in the Jurassic rather than algae take that niche. Again, algae cannot exist on land.

Starfish cannot even leave the water. And their lack of brains will be a disadvantage, especially when all the land animals have been evolving to be more intelligent. And if even 1 species of amphibian survives they will be able to outcompete all the echinoderms in the world.

Why? No life on Earth has ever developed into balloon forms. And again, conifers will outcompete them. Conifers are better adapted to land. Flowering plants are better than conifers because with the symbiosis with animals they spread faster. This world is impossible.

if you want to know large amout of forest near beeches was canged to the swamps and was beacame colonised by this algaes,

milions of years later during the drying of the swamps, algaes transformed their earth cointeiners into baloons of hydrogen

So you're also doing a different geological history?

Again, algae won't do that. They might live in the swamp (in fact they do so today), but that doesn't mean they won't go on land. Algae had the chance to do that during the Oligocene cooling, yet they didn't. Because they can't. They either 1) have no structural support to go on land or 2) they exist as pond scum, which won't go into grass-like forms.

Even if they were to (which they can't) if they were to be filled with air and grow huge then 1): animals starve if their filled with a common gas like oxygen or 2) they deplete all of the gas if they have a rare one like hydrogen. And if their small they get squashed and popped. They won't survive.

No the swamps was created because large amout of forest near beaches was hited by a tsunami wave

?????

The flooding of a tsunami might last a week at most, but not long enough for anything to to pop up, except for a few tidal wave critters like octopi. I'm sorry, but this world is just not plausible. Instead you can try making a new topic with similar creatures in the Habitable Zone forum?

pando,whats worng with this,this is alternative world and alternative worlds can look bizare.There can evolve air ecosystem with floating plants..
but i think that surviving flowering plants diverse,ichtyornis stay at water and have seal like lifestyle..mammals retake niches left by dinosaurs

bambiraptor evolve into flying form and create lineage of pseudobirds...they can look different than birds,maybe they still have got teeth

surviving squamates diverge too

however the tsunami wave was created by the meteorite hit and caused large amout of water on the beaches and nears

But the water 1) Doesn't stay and 2) there isn't enough water! Seriously, there are already swamps. Tsunamis were made by the real KT asteroid and yet they didn't make any new swamps.
