A prehistoric walk in the park
Looks like it’s not always asteroids.
The fossils were discovered in the Parnaiba Basin of north-eastern Brazil, and are some 278 million years old, corresponding to the Permian period, when all the continents we know today were still fused together.
Recent fossils unearthed in the Chinese province of Daoxian come to unravel the story of humanity’s spread as we know it today. The find consists of 47 teeth, belonging to modern humans, but what’s really important is their age – they have been dated to 80,000 years ago. This number doesn’t fit with the “Out of Africa” migration theory, holding that humans originate and have spread from the horn of the continent all around the world. The theory as we know it can’t explain human presence in the area for another 20,000 years.
Paleodictyon is a mysterious fossil pattern found mainly in marine sediments thought to be specific of a certain paleo-depth range; it is a relatively widespread trace fossil – called this way because it is mainly accepted that it is created by a burrowing creature. Although it has been discovered since the dawn of geology and fossil hunting, no one was able
Billions of years ago, the Earth was unrecognizable from the life supporting paradise it is today. Fossilized raindrops from some 2.7 billion years ago, conserved in time as rain dropped onto volcanic ash during an eruption, which eventually solidified into rock known as tuff, has revealed some very interesting facts about Earth’s ancient atmosphere. The discovery will help scientists understand more
Two days ago, the whole world was teeming with excitement, after some NASA researchers reported finding traces of alien life in meteorites; now, even their employer distances itself from them, and the whole scientific world seems to frown upon this work. However, in what is a very unusual move, NASA has denied any involvement with the paper, and even the
It was more than 300 million years ago that reptiles made tracks on earth. The exact moment when this happened is unknown, however; oh, and by exact moment, I’m talking about pinning it down to a couple million years (you gotta love geologists for their sense of time). So, a discovery of fossilized footprints was recently made in the Bay
Every once in a while archaeologists (and sometimes amateur archaeologists) make remarkable discoveries. Sometimes, the finding is so surprising that they are unable to explain what it is they’ve found, how it came into existence, or ascertain its value. This is list of such unexplained artifacts; artifacts that many believe should have never existed, or for which we have no satisfying explanation.
