Porphyrios: The Sea Monster that Terrorized the Late Roman Empire

The sixth century historian Procopius, in both his History of the Wars, and The Secret History, mentions a sea monster--a gigantic whale--named Porphyrios that dwelt in the Bosporus Strait and the Black Sea, and which terrorized the shipping lanes around Constantinople for about fifty years, and which causes significant headaches for the Emperor Justinian & the Roman navy. Our information is fairly limited, but what can we say about this real life Moby Dick?

Archaeological discovery made beneath a Paris train station

In today’s video we're going to delve into an incredible archaeological discovery made beneath a Paris train station: an ancient necropolis dating back nearly 2,000 years. Located beneath the bustling Port-Royal station on the historic Left Bank, this lost necropolis belonged to the Gallo-Roman town of Lutetia, which is modern-day Paris. The site was overlooked during the station's construction in 2014 and was only discovered when plans for a new station exit were announced.

The Dodo Bird: 5 Things You May Not Have Known

Although the dodo became extinct in 1690, this bird was more complex than you would realize.

Dodos were odd birds. According to popular belief, the name "dodo" derives from the Dutch word "dodoor," which means lethargic. But after examining its anatomy, scientists believe it was capable of running quickly.

The dodo, however, was not swift enough to escape its fate. The dodo was ready to believe the human settlers who came to its island because it was living on an island without predators and this led to its eventual extinction. Here are five additional facts about the dodo that you might not be aware of.

1 Weird Appearance

Dodos, which descended from Asian pigeons, lived on the Indian island of Mauritius. It had a massive head, a big hooked-tipped bill, and short legs. It weighed roughly 50 pounds. Most notably, their pectoral muscles weren't powerful enough to fly, and their wings were too short. Most likely, evolutionary biology is what led to this.

Dodos evolved to become larger and lost their capacity to fly since they were no longer need to use flight to flee from predators. Ostriches and penguins are two more birds that once flew but have since lost their ability to do so.

2 Reproduction

Despite the fact that many birds lay multiple eggs at once, it has been assumed based on eyewitness accounts that a female dodo would only lay one egg at a time. They would construct their nests on the ground and encircle them with grass as they were incapable of flying.

Up until 1638, when Dutch settlers began to arrive in Mauritius, the dodo population was thriving. The dodo population never rebounded once people moved in and started killing them; finally, they became extinct.

3 Extinction

The dodo had all the food it needed to survive, thrive, and live in safety in Mauritius for many years. As was previously said, that is, until a Dutch settlement arrived up. Contrary to common perception, settlers didn't enjoy the taste of the dodo bird, and their consumption did not cause the dodo population to decline.

Rats, monkeys, dogs, sheep, and pigs were just a few of the creatures the immigrants brought with them that decimated the dodo population. While humans harmed the trees where the dodos resided, these animals destroyed nests and ate the eggs. Although experts put the period as late as 1690 in 2013, the generally accepted extinction date is 1662.

4 They Weren't Stupid

"Ignorant," "dummy," "moron," and "dull" are a few synonyms for "dodo." However, dodos were not naive. Their brain-to-body ratio, according to research, indicates that they are of average intelligence. Dodos also have a big olfactory bulb, which improved their sense of smell. Birds usually rely on vision, thus this is rare for them.

5 Researchers May Try To Bring Them Back

Beth Shapiro, an evolutionary researcher, explores isolated areas in search of fossils from which to extract the DNA of extinct species. Her research has primarily concentrated on the dodo among other animals. She stated that the dodo had been fully sequenced earlier this year, albeit the results had not yet been made public. She has shown interest in the prospect of reviving the dodo.

According to her in an interview with Smithsonian Magazine, "if the dodo were to be brought back, it could be restored to protected habitats on [the island nation of] Mauritius, where people could go to observe dodos in their native habitat."

Dunkleosteus: One of the largest and fiercest sharks 380 million years ago

The name Dunkleosteus is a combination of two words: ‘osteon’ is a Greek word for bone, and Dunkle is named after David Dunkle. A well-known American paleontologist whose study mostly concentrated on fish fossils and is best known for his work in vertebrate paleontology at the Cleveland Museum of Natural History.

This placoderm is reputed to consume anything, or at least most things, and is extremely fast and powerful. The Dunkleosteus is one of the biggest placoderms ever to have lived and is said to have been one of the fiercest during the Late Devonian era, often known as the ‘Age of Fishes.’

The Dunkleosteus was known to weigh up to 8000 lb (3600 kg) and have a length of up to 346 in (8.8 m). D. terrelli, D. Belgicus, D. denisoni, D. marsaisi, D. magnificus, D. missouriensis, D. newberryi, D. amblyodoratus, and D.raveri are the 10 species of Dunkleosteus.

They are noted for their strength and ability to move their jaws swiftly, allowing them to effortlessly hunt animals. Dunkleosteus fossils have been discovered in North America, Morocco, Poland, and Belgium, among other places.

The Dunkleosteus appears to be an intriguing animal, however, there is little information known about it owing to extinction and age (it existed 360-370 million years ago). While nothing is known about many areas of the Dunkleosteus body, substantial information has been gathered from Dunkleosteus fossils and reconstruction.

The Dunkleosteus was revealed to have a two-part bony and armored exterior. It has two pairs of sharp bony plates that form a beak-like shape. Reconstructions have also revealed that certain Dunkleosteus species possessed pectoral fins, suggesting that the fin pattern in placoderms is heavily impacted by mobility needs.

Dunkleosteus terrelli is distinguished by its shark-like look and a prominent front lobe on its tail. The Dunkleosteus was the most powerful fish alive during the Late Devonian era. It is reported to reach 346 in (8.8 m) long and weigh up to 8000 lb (3600 kg), making it one of the biggest placoderms ever to have existed.

The Dunkleosteus is recognized for its large and muscular physique, as well as its enormous biting force capable of effortlessly chopping ancient sharks. A Dunkleosteus is one of the biggest fish species ever known to exist. They may weigh up to 8000 lb (3600 kg), making them large creatures.

Dunkleosteus was not a particularly excellent swimmer, according to legend. Because it was usually found in shallow seas and oceans, its bone structure was adequate to defend itself against other species, and its abundance did not cause Dunkleosteus to travel deep into the sea in search of food. The Dunkleosteus was a sluggish swimmer due to its thick and bony body and armor-like bone structure.

The Dunkleosteus had a system known as four-bar linkage, which allowed it to extend its jaw quickly and deliver a strong biting force while shutting the mouth. The pressure produced aided the Dunkleosteus in cutting through any cuticle, dental build, or armor.

As a result, it is thought that, in addition to ammonites and other placoderm fish, sharks, and other free-swimming species, they are also known to devour fish from their own species when hungry. This is reinforced by the discovery of fish bones and other semi-digested or indigested elements in the fossils.

Dunkleosteus’s habitat is unclear, although it has been reported that Dunkleosteus has been discovered in shallow oceans across the world. It is thought that Dunkleosteus was one of the first creatures to reproduce sexually via the mechanism of egg fertilization. The lifetime of a Dunkleosteus is unclear, although it existed during the Devonian period 360-370 million years ago.

Dunkleosteus is regarded as one of the most hazardous sea predators. Many characteristics have been linked to this armored predator, making it one of the most hazardous placoderms. The major causes are its cannibalistic nature and its ability to bend metal.

Scientific Evidence of Conflict Between Neanderthals and Cro-Magnons?

The Neanderthals were cooperative big game hunters, just like lions, wolves, and modern humans. These predators, at the top of the food chain, have few predators of their own, and competition drives conflict over hunting grounds. The same issue affected our big-headed evolutionary cousins; if predators didn't limit their population, conflict would have resulted.

Indeed, Humans have a long history of territorial behavior. Intense territorial conflicts also exist among chimpanzees, our closest living relatives. Male chimpanzees regularly form groups to ambush males from opposing bands, a behavior that is startlingly similar to human warfare.

Modern Humans frequently experience interpersonal conflict, and Neanderthals were very similar to us. Our DNA is 99.7% the same, and our skull and skeletal structures are remarkably similar. Neanderthals were astonishingly similar to us in terms of behavior.

The evidence from archaeology shows that Neanderthal lives were anything but tranquil. Warfare during the prehistoric period leaves traces. Due to the effectiveness of clubs as quick, potent, and precise weapons, prehistoric Homo sapiens and Neanderthals frequently exhibit skull trauma.

In point of fact, a new study reveals that a vicious attack on a Neanderthal caused a fracture in a 40,000 year-old skull. A computer reconstruction of the St. Césaire skull, discovered in France, led to this conclusion. According to the authors, their findings have significant ramifications for comprehending Neanderthals' social interactions with modern humans.
