Most paleontologists and geologists believe that dinosaurs existed between 220 million and 65 million years ago. Meanwhile, the ancient Homo sapiens were declared to appear about 200 thousand years ago. This shows that dinosaurs and humans could not live in the same era. However, the process of discovering archaeological sites discovered a lot of evidence that denied this view. Acambaro statues in Mexico are one such example. In July 1944, Waldemar Julsrud, a German merchant, stumbled upon a dinosaur-shaped statue while on his way to a mountain in the city of Acambaro (Mexico). Being an antique collector, Julsrud immediately realized the strange feature of this statue.
When it comes to the Carbon Age, people will immediately think of it as the era of giant insects like meter-long arthropods, large dragonflies like birds, but in reality The most terrible "killer" of the Carbon era is not a land or sky creature, because they are simply giant predators lurking on the bottom of rivers and lakes. One of them is the famously ferocious fish - Rhizodus hibberti.
The researchers discovered the fossils of a multi-finger finfish that lived on Earth in the late Devonian. The team's discovery in Australia and Canada is one of the most complete fossils of the lobe finfish. The 1.5 meter long fish was found in Miguasha, Quebec in 1938. It belongs to the Elpistostege watsoni, the largest predator that dominated the shallow and estuarine environment in Quebec 380 million years ago. The sharp fangs help them eat the big fish of the same area.
Is there anything in nature that can make Megalodon fear when confronted? The ancient super whale Melvillei is the answer. Megalodon super shark which is famous for being an ocean killer with a size of up to 20m and a bite to create the force equivalent to 11-18 tons is enough to cause a car to be crushed. With such aggressiveness and terrible size, Megalodon became a dangerous predator for sea lions, dolphins, and whales ... But whether in nature there is anything that can make Megalodon fear when confrontation or not? The ancient super whale Melvillei is the answer.
In 1965, fossilized remains of a dinosaur egg were found in Japan. Recently, the press quoted experts as saying that it was the fossil of the new dinosaur. Mainichi said the archaeologists confirmed the fossilized egg of a new species of dinosaur called Multifissoolithus shimonosekiensis. The research article was published March 16 in an academic journal published by the authors of Fukui University University and the Fukui Prefectural Museum of Dinosaurs. The Fukui Prefectural Museum of Dinosaurs is known as a major center in Japan, specializing in research on extinct species. According to the March 16 announcement of the Shimonoseki city government, the fossil egg was found in September 1965 by Yoshiharu Shimizu, a high school boy in the upper Ayaragi River, in Shimonoseki city. Yamaguchi Prefecture, Japan.
The researchers found the tiny rice-like worm-like creature, the oldest ancestor on a pedigree tree consisting of humans and most animals. The worm-like creature called Ikaria wariootia lived 555 million years ago. It is considered the earliest symmetric species to appear. Symmetrical animals on both sides have front and back, left and right. Geology professor Mary Droser and PhD student Scott Evans at the University of California, Riverside, USA, looked at fossils dating back to the late Ediacara period 555 million years ago in Nilpena, South Australia, due to the impact. symmetrical objects created by the two sides. But the researchers found no evidence that any species lived in caves. Upon closer inspection, they saw an oval trace near the cave.
Currently, because the iron chest has not been opened yet, many people who know about the incident have speculated that this is a chest containing gold bullion abandoned due to a period of turmoil before. The mysterious iron box was unintentionally discovered at a depth of 8m by construction workers in Dawson City, Canada while this group of people was conducting underground digging at the construction site. The large iron ark is estimated to exist from the 19th century and is currently causing a stir by what is not touched inside.
100 million-year-old fossils found in Africa reveal three species of giant fly pterosaurs, with wingspan of up to 4 meters. The findings, published in Cretaceous Research, are helping to explore the lesser-known evolutionary history in Africa during the dinosaur era. Toothed pterosaurs were once part of the ancient river ecosystem of the black continent, home to many predatory species such as crocodiles and predatory dinosaurs. "The pterosaur pterosaur is mostly known in Europe, South America and Asia. The new discovery is so interesting. It opens a door into the world of pterosaurs in Africa during the Cretaceous. ", lead researcher Megan L. Jacobs, a geoscientist at Baylor University, USA.
Millions of years ago, the early humans had small brains, throwing themselves from tree to tree like monkeys and ate only plant foods. 3.6 million years ago, the early "Small Legs" (the left is the model; the right is the skull) swings people from tree to tree. Scientists in South Africa discovered this after a CT scan of an ancient fossil skeleton called "Small Legs." This set of bones is from the Southern ape hominid that lived about 3.67 million years ago. This is the most complete skeleton among the skeletons collected so far. Experts compared this famous fossil with other fossil samples in Africa, and with modern human bones and today's chimpanzees. The results suggest that our ancestors had a different head motion from modern humans.
How do paleontologists calculate the weight of a dinosaur? How to calculate the weight of a dinosaur
One thing that most of us probably know, dinosaurs is the largest animal ever to appear on Earth. Some of them can reach super huge sizes, maybe even heavier than 70 tons. But in fact, we cannot see a flesh-and-blood dinosaur today, so how do we know their weight? At the end of 2019, the famous paleontologist Gregory S. Paul also conducted a systematic study of this issue. See how he measures the weight of these dinosaurs. And some points of view about calculating the weight of extinct animals at this stage.
