Also small cats, which can survive off rats, insects, small birds, reptiles, and amphibians.

It's a possibility, but it's more likely that Viverrids would survive.

And it's possible that the water chevrotain would survive as well. They will and do eat insects, fish and will scavenge as well, and are also semi-aquatic. Though it might be a bit of a stretch.

According to Wikipedia, terrestrial planets returned within a few years due to the atmosphere clearing. Saying that all strictly herbivorous species would go extinct seems questionable as a result, depending on the degree to which the atmosphere is rendered opaque. For example, could it be rendered opaque to the extent where formerly shade-dwelling plants moved into places that used to be bright and sunny? As someone who does gardening, some plants do very well in rather dark areas--for instance, some bottom-dwelling rainforest plants.

However, any herbivores that hung on would probably be fairly small.

Well, there will be surviving herbivores, most importantly insects. Bigger animals have a harder time surviving though, and if it wouldn't be for their metabolism and other factors, crocodiles and snakes would have went extinct too. If Crocodiles or snakes were herbivorous, we'd have our surviving vertebrate herbivores right there, but they're not, so the herbivores are further down the line.

Also, the full extent of the darkening of the atmosphere differs from source to source. Some even go as far and say that plants nearly completely vanished during the time and earth was covered in fungi feeding on the decomposing remains. Regardless of how bad it was exactly, to my knowledge there was not a single strictly herbivorous or carnivorous mammal species that survived the K-T-Event.

The only terrestrial mammalian survivors would be fairly small animals that are known to be very adaptable.

Actually some large mammals may of appeared before the K/T, like Ferae, Meridiungulates(Kharmerungulatum), and "Condylarths" for example.

Do we definately know that they survived the K-T event? It could also be similar to what happened to crocodiles: The small members of the group survived and grew back into the vacant big-sized niches.

Especially if raccoons are surviving, so would rhesus monkeys. And what about badgers, they're omnivorous. And small weasels, as least weasels hunt small rodents, who would survive as well. And if raccoons are surviving, so would foxes, as they are small and omnivorous as well, unlike what the list said that Canids "consists entirely of top predators".

I must admit, I was thinking very long about badgers. They together with the skunks are the two most likely candidates within the carnivora to survive, but I do believe that the skunks have a slight edge over badgers.

EDIT:Maybe even mouse lemurs could survive? They're omnivorous and small.

Mouse lemurs live in rainforests... :/

I will admit to being biased in favor of cats, though.

Yeah no, if small dinosaurs that fed on similar organisms didn't survive, I don't see why cats would.

Kharmerungulatum was small, but not small, like a small deer, I could be wrong though. "Condylarths" were small as well, but not that small. And while the basal Ferae are mysterious, only known by the molecular clock, from what we know from basal Carnivores were weasel-vivvarid sized. But we don't exactly know.

So generally, they were small (chevratain-weasel sized,). But Big enough to say that larger/specialized animals would of survived than what you have on your list.

Gray mouse lemur is the most common species, and it's range is different than what you think.

Here it's range.

Here's the madagascan biomes.

They can go into torpor, which odd for primates. But that will aid it's survive.

It would have to be an asteroid. Any nuclear war large enough to cause 80% of species to go extinct due to radioactive particles in the air is probably going to drive a lot more extinct due to the fallout. As far as humans, let's just say we said, "Fuck this, I'm out of here."
It's a little difficult for the entirety of humanity to get up and leave Earth collectively.

A much more interesting scenario would be something akin to Elysium. The rich and generally favorable are given opportunity to leave Earth for an off-world colony. The poor and degenerates are left to suffer the consequences of a damaged Earth. Imagine the short-lived societies that develop, the conflicts that occur, the implications of a classist divide within humanity that seals extinction. What becomes of the humans left on Earth ? What about the animals - are new species domesticated and bred or killed off ? You can do so much with such a simple concept.

I understand that's not the approach of your project but it's such a good idea to say the least !

Well, mostly what I was thinking of were things like rabbits. Given their explosive rate of breeding, the wide distribution, and the fact that it's nearly impossible to drive the damn things extinct even when you're trying to, and it seems unlikely that the entire clade would up and die.

At the risk of being overly argumentative, small dinosaurs that fed on similar organisms did survive, if I remember correctly: Birds.

I'm fine with doing away with most primates, but I'm not sure about bushbabies (galagos) because they are small, very diverse, and found through most of Africa. Here's information on the genus Galago. Not sure if they would go extinct or not, but it's at least worth learning more about them.

I should also point out that I don't believe there's been much study as to the effects of the K-T Event on island communities. I suspect that life on most islands would be whipped out, so this is something worth exploring

I'm also on board with saving rabbits, *B*U*T*, I can understand why you would lsit them as going extinct, so I'm not certain if that is worth revision or not.

Also, another reason oilbirds go extinct: their frugivores and if plants are so greatly impacted that species dependant on them are whipped out, then so to must oilbirds.

I also don't understand why you're whipping our insectivorous birds (specifically nightjars), but not insectivorous mammals (let's say, bats, for example). I'm not saying you're wrong in this decision, I'm just point out an inconsistency that may need further explanation. For example, perhaps the fact that they nest on the ground may play a part in their extinction.

All this said, I am looking forwards to how you handle the arthropods (being an entomologist-in-training)

Wow, so much animals that became extinct. Also, aren't pigs able to survive? Also, not all megafauna should be dead, why won't you revive camels, pigs, horses, antelopes and deer. That's the only ungulates that have a possibility of surviving.

Also, cows can survive as well. I don't believe that dogs and cats would become extinct, I see, I think that you want to change the extinct groups because a lot of users are already criticizing. But I don't see why people are saying to let rabbits extinct when they're diverse and eat a variety of plants.

They seem to be best primate candidate to survive, it seems that they became somewhat adapted to deforestation by being smaller, but still, its quite restricted in range to certain parts of an island..

Esto no es exacto. Es tan irritante como hiciste reglas tontas como límite de tamaño, dieta, etc ejemplo, los conejos son adaptables, los gatos son adaptables, algunos primates son muy adaptables etc Algunas áreas no sería ese derecho afectado? Así que algunas de estas áreas se puedan acoger algunos restos, como en el caso de Islandia, el caballo podría sobrevivir. Incluso yo, un niño de diez años, puedo tomar mejores escenarios que tú.
