How the darkness and the cold killed the (non-avian) dinosaurs

Now we have a computer simulation of how the afterward effects of famous Chicxulub asteroid (estimated to be 10 km/6.2 mi) wide) killed the non-avian dinosaurs (and also a wide range of other species). On January 13, 2017, an article titled “Baby, it’s cold outside: Climate model simulations of the effects of the asteroid impact at the end of the Cretaceous”, published by the Climate scientists of Potsdam Institute for Climate Impact Research (PIK), revealed a detailed model of what happened to the atmosphere and the climate after the Chicxulub impact.

Top 6 largest fish species

Here are the top six largest living fish species (within around 33,100 described species) in the world. But, before answering “what is the biggest fish”, we must answer “what is a fish?” At first, it looks like an easy question, but in fact it is not. There are a wide range of animals we call “fish”, so it is not easy to define what makes a fish “a fish”.
