Tracing Whale Evolution: Origin of Cetaceans
Whale evolution is an enigma, it is a testament of the potency of evolution by natural selection, in shaping organisms to whatever ways the environment demanded. Just a century ago, no one would have guessed that whales were descended from a small deer-like animal.
They underwent a drastic change from a racoon-sized land-dwelling animal to the biggest animal to have ever existed on the planet, and in between, they took the shape of uncanny otherworldly creatures.
In this video we take a look back at one of evolution's most epic tales and the bizarre animals whose remains taught us the story.

Every Tyrannosaurid, explained.
Просмотров 93 тыс.Месяц назад
Tyrannosaurus rex is a name we're all familiar with, it's the most popular dinosaur and is most likely the one that introduced us to the wonderful world of paleontology. But do you know that T. rex isn't the only Tyrannosaur? Tyrannosaurus, Daspletosaurus, Gorgosaurus and others are all members of the Tyrannosauridae family. The Tyrannosauridae comprises of 18 genera of tetanuran theropod dinos...
Every Spinosaurid, explained.
Просмотров 383 тыс.4 месяца назад
Spinosaurus, Baryonyx, and Suchomimus have something in common; they're weird, and they're also members of a clade known as the Spinosauridae (or spinosaurids)! The Spinosauridae comprises of 20 genera of tetanuran theropod dinosaurs, but some of which are no longer a valid taxon and some others have disputed validity. All 20 genera of those dinosaurs, however, are included in this video. Liste...

Holocene Extinction, explained.

Holocene Extinction or Anthropocene Extinction, often referred to as the sixth mass extinction, is an ongoing global event characterized by a significant and rapid loss of biodiversity. It is primarily caused by none other than our own activities. Humans have modified the surface of the planet to suit our needs irresponsibly. Climate change, deforestation, habitat destruction, pollution, overfi...

Pyrenean Ibex: The Animal That Went Extinct Twice

Holocene Extinction Episode 5: The Pyrenean Ibex The Bucardo or formally known as the Pyrenean ibex, was pushed to extinction by trophy hunters who hunted the ibex for their iconic, long, curved horns and the introduction of human livestock, which competed with the ibex for grazing area. Three years after the Ibex went extinct, however, the last individual of the species was resurrected through...

Holocene Extinction Episode 4: The Great Auk The Great Auk or Pinguinus impennis is the equivalent of the penguins in the northern hemisphere, in fact, the early sailors who ventured far into the Antarctic seas in the southern hemisphere used the great auk's generic name "Pinguinus" to call the flightless birds there now formally known as "penguin" due to their similar appearance and probably b...
The Search for the Thylacine
Просмотров 42 тыс.Год назад
Holocene Extinction Episode 3: The Thylacine Tasmanian tiger or thylacine sightings have been frequently reported, in Tasmania and in Australia alike. The thylacine’s elusive nature combined with Tasmania’s vast wilderness allow for a possibility that the carnivorous marsupial still survives to the present day. Numerous searches and investigations tried to prove this optimism. However, it seems...
Why Sauropod's Nostrils Aren't So Obvious
Просмотров 13 тыс.Год назад
Brachiosaurus, Diplodocus, Argentinosaurus and many other sauropods are often depicted with nostrils high on their foreheads. It makes sense to assume this nostril position when looking at sauropod skulls, since their nasal openings are located on top of their skulls. But, having nostrils on the forehead offers no anatomical purpose to sauropods. A closer analysis into dinosaur skulls has figur...
Pachycephalosaurus: Are Stygimoloch and Dracorex Valid?
Просмотров 28 тыс.Год назад
In 2009, Pachycephalosaurus, Stygimoloch, and Dracorex, three unique dome-headed dinosaurs, were determined to be the same species. Dinosaurs ontogeny has caused confusion in the description of multiple dinosaur taxa, but none comes close to the case of Pachycephalosaurus. It arguably underwent the most remarkable growth curve amongst all other dinosaurs. Their crowns seemingly morph into diffe...

    • @FactorTrace

      Apart from the differences in localities and time periods in which they lived. There are differences in their bone shapes that don't always appear in the living animal, it's called autapomorphy. From these bases we are able to tell one taxon apart from the other.

    Why would they even need to get their torsos underwater? If the air sacs make them float like hippos, I can totally see them taking advantage of a cool lake. Might even be a way to get parasites off them as the fish would like it, and their poop.

    @nyoodmono4681 4 дня назад

    Well it is fear mongering.The stated "fact" that we lost 80% of species since 1500 is plane wrong.Most of a declnie happened after the holocene optimum,when the Sahara turned into a desert for example. Most paleonthologist do not agree on calling it a mass extincton.Elephants in south Africa are so abundent now, they destroy woodland. The forrests of Europe are 50% larger now, then in the age of sailing ships. The only thing correct is the problem with crop monocultures and insect diversity decline, but not due to herbecites, but wild space loss. Most of earth is still wild, the oceans anyway and on the the land all human infrastructure combined, would take "only" the space of Texas.
