"Scientists reveal species could have survived if killer asteroid had hit 30 seconds later" Well that's what happens if you're unlucky enough to be a dinosaur who's in the wrong place at the wrong time? http://www.mirror.co.uk/science/day-dinosaurs-died-scientists-reveal-104260 (whatever will NASA think of next for fake nooze? )
Thanks - trust the dumbos at the BBC not to miss it! Tell them you're a 'scientist' and they'll believe everything you say, no matter how barmy.
Likely the Dinosaurs die not die in a day, week, month or year...it probably happened over centuries at least.
And obviously not all of them died...their progeny get eaten all the time, especially at Thanksgiving.
So the dinosaur sounded like, "gobble gobble" And the attached image struck me that one cannot equate volume of brain between mammals, birds and probably dinosaurs because the later are wired diff. fershur Also it ain't all about neurons. I do believe all that "fat" glial activity in the mammalian brain does more that just nutritional support and scaffolding. Different, y'see. How about that? Save the applause and gimmie a "like".

Exactly so - they wouldn't be the first life form to become an endangered species unto extinction. Well having said that, perhaps they were the first, but there have been plenty of species which have become extinct since then, for one reason or another. I've never believed for a second this 'Dinosaurs were wiped out by an asteroid.' myth. 'They could have survived if killer asteroid had hit 30 seconds later'
Another 30 seconds would have put the impact site around 8 miles in a different location. The premise is that it was the specific location of the impact which caused colossal volumes of sulphur to be injected into the atmosphere. Not something you need to bang your head against a wall about. . . I suppose you took the title of the article a bit too literal.
From your initial post, you took it as the meteor landed on the dinosaurs and they all died instantly. But do tell, what aspect is full of crap?
Guess some people don't want to consider this strike in its full context that it wasn't just the dinosaurs that died in the aftermath. The entire ecosystem collapsed. You know that thing you learn in grade school about the "food chain".
So exactly where is this asteroid which was so enormous that its impact had global ramifications? They must have found it by now?
Calling someone a "bird brain" used to be a common insult, but actually bird's brains are far more efficient per size.
Do you seriously not understand this or are you just trolling? Just in case I will attempt providing an education you might understand: This is both a matter of scale and physical reality. The impact obviously was large and powerful enough to reach the ocean floor. The ocean floor is made of dirt. A large impact creates an explosion. An explosion is very hot. Heat vaporizes liquid. Such a large impact elects large amounts of material. These materials go very high into the atmosphere. These materials have been superheated and vaporized. Atmospheric currents do not stop moving. Vaporized materials are moved by these currents and distributed accordingly. Any liquid in in gaseous form until it rains. Superheated materials eventually fall to the ground by gravity. Hot materials light things on fire. Fire created ash and smoke. Smoke rises. Sunlight is filtered or blocked by smoke. I hope this is helpful.
At the bottom of the caribbean. How would you go about attempting to find a 65 million year old large hunks of rock on the bottom of a seabed? Of course they have plenty of geological evidence of the impact including but not limited to the debris field and the contemporaneous iridium layer found around the world.
Well I'll say this for you, tecoyah - you sure have got a vivid imagination. If what you say is true then I can quite believe it would have consequences for the locale, but global? No way Jose. If it had been global all other wildlife on the planet would have 'gone the way of the dinosaurs'.
" The volcano's Ultra Plinian eruption on June 15, 1991 produced the second-largest terrestrial eruption of the 20th century after the 1912 eruption of Novarupta in the Alaska Peninsula. Complicating the eruption was the arrival of Typhoon Yunya (Diding), bringing a lethal messy mix of ash and rain to towns and cities surrounding the volcano. Predictions at the onset of the climactic eruption led to the evacuation of tens of thousands of people from the surrounding areas, saving many lives. Surrounding areas were severely damaged by pyroclastic surges, ash falls, and subsequently, by the flooding lahars caused by rainwater re-mobilizing earlier volcanic deposits. This caused extensive destruction to infrastructure and changed river systems for years after the eruption. The effects of the eruption were felt worldwide. It ejected roughly 10,000,000,000 tonnes (1.1×1010 short tons) or 10 km3 (2.4 cu mi) of magma, and 20,000,000 tonnes (22,000,000 short tons) of SO 2, bringing vast quantities of minerals and toxic metals to the surface environment. It injected more particulate into the stratosphere than any eruption since Krakatoa in 1883. Over the following months, the aerosols formed a global layer of sulfuric acid haze. Global temperatures dropped by about 0.5 °C (0.9 °F) in the years 1991–93, and ozone depletion temporarily increased substantially." https://en.wikipedia.org/wiki/Mount_Pinatubo
Alright then, so how does Wiki explain how all other species survived the cataclysm? Or how do you explain it??
The species that exist today are ancestors of those smaller more adaptable or burrowing animals that were able to survive long enough to breed and take advantage of the new environment. Larger dinosaurs died off and smaller adaptable species became what we call birds today, Crocodilians and reptiles probably took advantage of the semi liquid environment, Mammals were primarily underground and microbial life likely had no serious problems. This is of course speculation as would be anything, anyone says...but it is based on observation and geological data.
