The blue whale (scientific name: Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). Up to 31 meters (102 feet) in length and 190 tonnes (210 short tons) in weight, it is the largest extant animal and also is the heaviest known to have existed. But it’s hard to conceptualize how big […]
By studying lunar craters, scientists have discovered that the asteroid impacts became more frequent about 290 million years ago. So was just a matter of time for dinosaurs to becoming extinct.
What if the Earth’s history (our planet’s age is approximately 4.54 billion years), compressed into just one year, let’s say the year of 2018? @YearOnEarth just did that. At midnight on the 31st of December 2017, Chris Jennings started a little project for the incoming year: tweeting the entirety of the geological history of the […]
Birds (Aves or avian dinosaurs) range in size and weight from the 5 cm (2 in) and 1.6-2 grams bee hummingbird to the 2.75 m (9 ft) and 104-156 kg (229-344 lbs) ostrich. Here are the top 15 largest bird species in the world (by body weight). Birds form one of six basic animal groups, […]
Around 66 million years ago, an asteroid or comet at least 10 kilometers (6 miles) in diameter impacted a few miles from the present-day town of Chicxulub in Mexico (hence it is dubbed as the “Chicxulub impactor”), at around 64,000 kilometers per hour (40,000 mph). The impact has created a crater (Chicxulub crater) more than […]
I stumbled upon an amazing web page showing what did ancient Earth look like. On the “Dinosaur Pictures and Facts” web page (dinosaurpictures.org), there’s also an interactive animation. On this page, you can either select the years (i.e. 600 million years ago) or jump to a particular event (i.e. first multicellular life) and see how ancient […]
According to the scientists who drilled into the Chicxulub crater buried underneath the Yucatán Peninsula and the Gulf of Mexico, the asteroid hit the “worst possible place”. They summarized their findings so far in a BBC Two documentary titled “The Day The Dinosaurs Died“. The documentary presented by professors Alice Roberts and Ben Garod.
Crocodiles are aquatic reptiles, and among the most feared carnivores on Earth, because of their size, big powerful jaws and aggressiveness. They are so successful predators – once they were living alongside the dinosaurs. After the Chicxulub impact, which happened around 66 million years ago, the non-avian dinosaurs were gone but crocodiles were managed to survive. Here are […]
Identifying the largest dinosaurs ever lived isn’t an easy task, because it’s very rare to unearth a complete fossil. Furthermore, only a tiny percentage of these amazing animals ever fossilized, and most of these “lucky” bodies will remain buried underground forever. So, we may never know exactly what dinosaur was the biggest (or the tiniest) […]
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 […]
