k t event

Disney’s Dinosaur is an exercise in nihilism as the events of the movie are rendered null and void when taking the canon of the franchise into account. Aladar’s actions to save his family prove pointless as, sometime after the ending of the film, the K-T extinction event takes place and everyone he loves including his sexy dino wife, his newborn babies, his adopted lemur family and his interspecies elder lesbian friends are brutally killed in the impact. He only survives due to the actions of a time travelling scientist determined to bring a living dinosaur specimen back with him into the present-day. In this essay we will explore the nihilistic themes present throughout Disney’s Dinosaur and its extended canon by-

Ecology & the Death of the Two Trees

What happened to the elves when the Two Trees of Valinor died?

Now I don’t mean historically - I have the Silmarillion for that. I mean scientifically what happened as a result of the loss of their light source, and what were the practical consequences for the elves.

Because I think the Undying Lands were dying.

This may be the wrong blog for this question but how is it that everytime Avian birds tried to fill a niche outside their usual ones they were replaced by more successful mammals? I'm talking about things like Gastornis and the terror birds being large apex predators, the thunder swans and their ilk being large herbivores, or even the mega penguins being replaced by marine mammals. Do birds just suck at not flying roles?

Flightless birds are really successful though, anon. Those that you mentioned went extinct for pretty specific reasons that had nothing to do with how well suited they we.re to their environment. For instance, Gastornis died from loss of rainforests, terror birds were offed in the Great American Interchange, and giant swans were a weird island taxon, and those tend to die out fairly frequently. 

Mammals are also going extinct all the time, just as often as birds. Mammals are for the most part terrible fliers because they have a large genome size, which is inefficient in an organism that has to use so much energy for locomotion. A lot of research has recently been done on the effects of genome size on vertebrate flight. See, we can extrapolate the size of an organism’s genome based on their cell size. Larger genome means a larger cell, because you need more cellular machinery to process that genome. As such, we can actually figure out the genome size for extinct animals, because fossils preserve bone cell shape and size. These studies have shown that vertebrate groups that evolved flight - pterosaurs, birds, and bats - all had really small genomes. Theropod dinosaurs - possibly Saurischian dinosaurs in general - also had really small genomes, showing this was a trend that was evolving for a long time in the lineage that lead to birds. Mammals, in general, have huge flippin’ genomes, and bats are sort of the one exception to that rule - look at humans, our genomes are crawling with “junk” (noncoding) DNA. (Note: this does not mean we are more complex. The roundworm C. elegans has more DNA in their genome than we do. Don’t misread me here.) So mammals are really poorly adapted for flight, meanwhile, birds in general are a group that has a deep ancestry of small-genome-ness. 


Why does a small genome mean an ability to fly? Well, our best guess is that smaller genome = smaller cells = everything is, over all, lighter and more efficient - and it takes a LOT of energy to fly, so efficiency is a must when it comes to processing the genome and going through metabolism. 


Mammals are terrible at flying, but having a small genome doesn’t make you terrible at living on land. In fact, it makes you pretty much better at everything.

 As a general rule, mammals were a lucky bunch who hit their mark exactly when they needed to, and probably wouldn’t have been nearly as biologically successful had they not had the right genes at the right time. Dinosaurs were one of the best animal groups ever, perpetuating more efficient than most others, even after the K-T Extinction Event, when all non-avian dinosaurs went extinct. Mammals have never propagated nearly this well.

Most of your comment has been a massive generalization that’s both misguided and a little misleading.

Get rekt.

Let’s take a moment to welcome our new Mr. Poe in Netflix’s A Series of Unfortunate Events, K. Todd Freeman! He has appeared in popular films such as The Dark Knight and Teenage Mutant Ninja Turtles, as well as several TV shows such as Buffy the Vampire Slayer. He has also been nominated for a Tony Award for his performance in "The Song of Jacob Zulu.“

HI. so, i am writing a novel in wich the world is going to end. an asteroid is going to hit earth and BAM !!!over!!! and i really need help to write how the humans are going to react. do you think that if the world was really going to end everything would be out of control and the goverment would freak out and lose control? i just really need help.

It depends on the size of the asteroid. If we’re talking K-T Event/Cretaceous Extinction kind of asteroid, then it’s doubtful enough humans – indeed, enough organisms bigger than domestic cats – would survive to sow the seeds of chaos.

Smaller asteroids are likely to cause regionalized disarray, uncertainty, anarchy, etc.

The problem with many post-apoc stories is that they focus on “the government” and that they assume the only thing a government can do is collapse. 

To address the first point, there are thousands of governments, from tribal systems to statewide bureaucracies. What governments survive and which ones fade away? In the absence of a larger body, local governments may become the law of the land. Perhaps local governments crumble first (unable to deal with the pressures of so many needy people) and it’s up to the might of the larger governments to save them. Governments may simply cease to exist altogether. If an asteroid hit Montenegro or Andorra, the entire country would be flattened. Boom. Gone. Also, governments will appear. The desire for order is strong and disaster brings out the best as well as the worst in people. (To address that point – quit making people evil bastards the moment the cards are down! Of course those people exist, but heroism exists alongside debauchery in desperate situations.) 

To address the second point, a government in crisis can do many things:

  • Relocate. The most important body of government moves to another, more stable location and issues laws/handles business from afar.
  • Collapse. Just falls apart. Poof! It’s overworked and its workers leave so they can look after their family.
  • Stay together! The crisis invokes a “rally ‘round the flag” mentality and citizens look to and support their government any way they can. As a result of this mentality, the government retains its power and authoritative voice.
  • Become absorbed into another government. The government is unable to handle the demands the crisis puts on them and appeals to a higher power, be it a stable power or a tier higher in official authority. The weak government becomes absorbed or subservient to another as a way to survive. This can be good or bad, depending if a) the stronger power gives the power back, b) the weaker government wants the power back.
  • Be conquered. Another group takes advantage of the crisis and sweeps in to dispose of their weakened enemy.
