Dolphins Used To Be Terrifying...

Flipper wasn't so nice and wholesome back in the day. For some reason it seems like every animal we all adore was at one point quite monstrous as demonstrated by the Ankylorhiza, a prehistoric nightmarish dolphin.

Trouble with the fossil finds is they can pretty much make the fossil say what ever they want within reason and still have no idea what the creature was like originally. How many times have they changed what this or that fossil creature was like? I think there is far too much guess work and wishful thinking.

Odontocetes (toothed whales) first emerged at the start of the Oligocene, and it wasn’t long before they too produced some scary marine predators. The most successful and famous would be the various lineages of raptorial physeteroids-the “killer sperm whales”-but they were far from alone. One of the first odontocetes to function as an apex predator was Ankylorhiza tiedemani. At around 4.8 meters long, this animal was the largest odontocete from the Oligocene, and had one of the most formidable sets of jaws and teeth; its jaws were more heavily built than in its smaller relatives, and its teeth were not only robust, but equipped with cutting edges both front and back. The anterior incisors at the very tip of the jaws were especially large, and they protruded forward to the extent they would likely have been visible even if the animal’s mouth was shut. These were not the teeth of an animal restricted to small fish and squid that it could swallow whole. Ankylorhiza was eating larger fish, sharks, and other cetaceans. For the entire history of cetaceans as a dominant group of marine predators, they were facing competition from a less diverse but equally successful group; the otodontid sharks, most of which are nowadays considered a series of descendants belonging to the genus Otodus. During the Oligocene, the otodontid shark that acted as Ankylorhiza’s rival was Otodus angustidens, which was large enough that it may actually have been capable of preying on Ankylorhiza, though for the most part they likely hunted similar types of prey. In the following Miocene epoch, other lineages of odontocetes (including new lineages of raptorial physeteroids and large squalodonts) would take up Ankylorhiza’s legacy, while O. angustidens would quickly produce two larger descendants-O. chubutensis, and the infamous O. megalodon.

[@Moosyfate]

Not to be disrespectful of your take, but it seems to make more sense that the front facing teeth were used for rooting in the seafloor, and the tooth damage and bite power would make more sense if it was chomping through something tough. My guess is that it had a regular diet of mollusks and the like.

[@SewingBoxDesigns]

Interesting point! But being dolphins, they probably used them like a multi tool.

[@DG-iw3yw]

How do you get purchase to do that underwater? I can imagine a walrus doing something like that, with its body weight and size, and locomotive ability, but not so much a dolphin, but those outfacing teeth tend to converge with other species that specialise in catching fish

[@bigboss-tl2xr]

The art in the thumbnail of this video where a prehistoric dolphin attempts to eat a prehistoric monkey is based off the 1778 painting, Watson and the Shark by John Singleton Copley, and after finding this out, a British merchant later Baron named Brooks Watson was attacked by a shark as a 14-year old cabin boy in Havana, Cuba in 1749 where his rescuers successfully got him out of the water after he was attacked after three attempts. The story was well known and helped Copley paint the picture and it still exists in DC's National Gallery of Art.

Great video, I learned a lot. As an ichthyologist, I feel compelled to correct one small mistake you made. When you said “saw shark” you showed a picture of a sawfish, which is a Ray, not a shark.

8:15 - 8:20 he talks about how they’re only found in one small area? He forgot about the very common behavior of marine mammals to migrate to specific areas to breed and likely die. These dolphins didn’t have a restricted territory, they’re probably just being found at one of these spots they would migrate to (Edit) In fact, I’m almost positive that these dolphins are identical to modern dolphins in this way. There’s no way in hell an apex predator with speed on its side would only be in one small area. It might have hung around there often for the abundance of food in the warm surface waters, migrated there to breed, maybe even die, but it probably didn’t live there exclusively
