Whales are the largest animals of ALL TIME… At one stage of their evolutionary history, they lived on land! In this new series, palaeontologist Ben Francischelli will be documenting this remarkable step-wise transition to the water… but the first question that needs to be answered: Why did the whale go back into the water?
Explore the museum’s rich collection of prehistoric whale specimens in a 3D immersive environment accessible anywhere, any time! This virtual gallery unites information and fossils that are spread across museum exhibits, with a bit of additional information, to tell the story of how whales evolved from ancient land mammals into the water-adapted creatures we know … Meer lezen
Zo’n 93 miljoen jaar geleden zweefde een bizarre, plankton etende haai door de zee in wat nu het noordoosten van Mexico is. De ‘adelaarshaai’ gebruikte daarvoor vreemde, zeer lange, vleugelachtige vinnen die zijn lichaam breder maakten dan het lang was. Geen enkel ander in zee levend wezen dat we kennen, heeft een dergelijke lichaamsbouw. >> … Meer lezen
If you’ve ever seen a manta ray, you may be able to imagine what the ancient eagle shark looked like in action: a giant, ghostly figure flapping through Cretaceous era seas near present-day Mexico. For the first time, paleontologists describe the new species, discovered in a limestone quarry in northeastern Mexico in 2012, today in Science.
Today, we know that the Basilosaurus is the first ancient whale humanity has ever found. But back when it was first described, the animal’s huge proportions earned it the name of ‘king lizard’. And although technically incorrect, the name isn’t undeserved; during its day, the Basilosaurus ruled the waters of Tethys with an iron flipper … Meer lezen
Almost 700 years ago, a Dutch naturalist envisioned a fish with arms that would enable it to climb out of the water, setting the stage for terrestrial life. Now, it turns out, his fantasy had roots in reality. Researchers studying skeletons of the finger-size zebrafish have discovered mutants that grow extra bones in their front … Meer lezen
A 24-million-year-old fossil of a giant tusked dolphin lacks several features common to modern dolphins and baleen whales. The discovery shows that the common ancestor of dolphins and whales lacked these features, meaning the same adaptations for swimming must have evolved independently in both lineages. >> read more … image credits: By PaleoGeekSquared – Own … Meer lezen
