itt: pictures of dinosaurs gazing haplessly at the arriving meteor

some earlier theories here

http://www.history.com/topics/why-did-the-dinosaurs-die-out

going off by what i learnt over 15 years ago but wasn't it a meteor and climate change that caused their extinction?

oh pre-that i think one was flatulance wasn't it?

shouldn't rely on comedy skits to teach me stuff tho

the very early theories of what created fossils tended to be semi-bibilical: that they were bones of creatures that hadn't survived the flood (or perhaps more than one flood, or some kind of catastrophic upheaval, there were various ideas)

dinosaurs were named as a species a couple of decades before darwin's published the origin of species and by the time they were being sought and taxonomised in number, the darwinist orthodoxy was gradualism rather than catastrophes (stephen jay gould wrote several interesting essays on this, not least bcz he thought that "punctuated equilibrium" was the process: in other words not a pure gradualism)

the alvarez thesis was a big deal, in 1980 -- not least bcz it got caught up by the anti-nuclear movement, who extrapolated the idea of nuclear winter from the alvarez proposal, that vast clouds of dust kicked up by the comet/asteroid had blotted out sunlight for decades, shifting the climate

shifting the climate

read this as shitting the climate

so what i remember from dad's books that he had as a kid is just that people handwaved the vanishing of the dinosaurs as ordinary evolution over a very long time and climate shifts maybe caused by varitions in the sun's brightness or whatever

(they also often had maps of the landmasses in various eras -- pangeaa and gondwanaland etc -- but continental drift wasn't established as the general scientific consensus until the mid-60s, so they handwaved how prehistoric animals had crossed large oceans with "vegetable mats", and draw in the likely routes the mats must have taken, across from africa to south america and so on: dad was a naturalist, more focused on plants than animals, but he said the conference where the consensus changed was a huge deal, lots of ppl went to it thinking they were the only ones who really believed in continental drift, and then they all realised everyone else had started believing it also, and the episteme changed overnight, and a lot of older naturalists basically retired as the embittered old school… he may have been dramatising a bit, but it was a very fast shift)

(the key new evidence came from sonar, invented in ww2, being used to map the ocean beds in the 50s and all the volcanic rifts which are the motor of the movement)

and that's how unicorns were born

according to Mr. Freeze in "Batman and Robin", it was the ice age that killed the dinosaurs

the permian was a much slower event than the cretaceous wipeout, but for some reason it's imagery scares me more. The anoxic oceans where 95% of life was wiped out and the bacteria dense pondwater giving the planet a sickly pink glow from space. And just the idea of choking to death in a nightmare hothouse world.

Yeah some of the CGI ones are alright but still prefer kid-drawn and lovingly hand-painted

I remember 'mammals ate the eggs' and flatulence - also pictures of large predatory dinosaurs always stood up on two legs roaring into the air

https://en.wikipedia.org/wiki/Chicxulub_crater

currently popular theory is this crater's time of impact lines up well with the major extinction period

(they also often had maps of the landmasses in various eras -- pangeaa and gondwanaland etc -- but continental drift wasn't established as the general scientific consensus until the mid-60s,

Did not know this - but they were aware of the landmasses having been in different place from I suppose sea-creature fossils found on land?

wegener had proposed continental drift back in 1912 -- based on the way africa so obviously fits into south america, and many other less obvious tesselations and geological similarities between jigsawed pieces -- but no one could think of a mechanism for the plates to move, as the whole crust was assumed to be solid, and the idea wasn't taken up

Always has to be at least two animal species on display

haha otm

long detailed essay in the rise of interest in exploring reasons why dinosaurs became extinct: http://palaeo.gly.bris.ac.uk/Essays/Dino90.html

author puts the turning point at the start of the 1970s

wait what happened in the 1970s that killed dinos

Glam rock.

prog rock dude

From that link, 'A Survey of Theories for the Death of the Dinosaurs' could make a good poll

This thread is not only great to look at but great to read, the same is not true of the, superficially similar, Paul Weller thread. Paul Weller not being anywhere near as interesting as dinosaurs, or with their enduring appeal (who knows though, eh?)

The asteroid theory is clearly being financed by kindergarten teacher special interest groups, who dread having to assign students to illustrate the rise of angiosperms.

kids still love dinosaurs, right? I remember being into them really young and practicing drawing brontosaurus necks

They have Dinosaur World near Lakeland here. The kids dig it

Thanks, y'all, for filling in so much backstory! Yeah, I now remember egg-eating mammals mixed in with death comet, in my childhood.

mark s, hope your lengthy and engaging posts are signs that all is well.
