David Schwimmer Talks Giant Crocodiles, Dinosaurs & Poo Eating Sharks

05-04-2010 2:23pm#1Hot on the heels of the dinosaur eating snake comes a dinosaur eating crocodile that even munched on tyrannosaurs! :eek:
As an interesting side note, one of the lead researchers of Deinosuchus is David R. Schwimmer, not to be confused with David Schwimmer, who in a daft coincidence, plays Dr. Ross Gellar the palaeontologist from the hit TV series Friends.Deinosuchus* tooth impressions in the bones of their prey tell the tale of titanic battles in which the 29-foot-long (9-meter-long) crocs took down dinosaurs their own size—including the T. rex relatives Appalachiosaurus montgomeriensis and Albertosaurus.
"One of the marks shows signs that the bone was healed, which means that the animal survived the bite," Schwimmer said.
Extraordinary news calls for an extraordinary image!

Interestingly enough it has also emerged that the local sharks dined on the mighty beast's feces.The team also found a fossilized shark tooth embedded in the outside of a coprolite. But because the tooth bears no signs of having been digested, the team suspects a shark left the tooth behind when scavenging on Deinosuchus droppings.

There was an inland sea in North America during the Cretaceous alright. That's where a lot of the mosasaurs lived. It is believed to be the sea most densely populated by large predators ever. Between the mosasaurs, giant predatory bony fish, great white sized sharks, giant squids, 5 foot long swimming birds... it wasn't a good place to take a dip. The giant croc Deinosuchus was very widespread, living all over America (on both sides of the inland sea) and also northern Mexico. It appears to have favoured salt water like the modern saltie, but it is unclear if it actually ventured out into the open sea marine environment. There would have been a lot of competition there. While it's remains have been found in marine deposits it is unclear whether it actually lived there or it's remains were simply washed out to see. The idea of a giant croc inhabiting the sea described as "Hell's Aquarium" along with all of those other monsters is too exciting to ignore though.
Here are various size estimates for Deinosuchus made over the years:
The documentary you saw may have been 'Super Croc' about Sarcosuchus and narrated by none other than Sam Neil (of Jurassic Park fame).
This is the museum model:

Yes I think it was the documentary about Sarcosuchus.
Wasn't it in South America? I am not sure now, because of the inland sea in North America with Deinosuchus in it. Hard to imagine two giant crocodilian species inhabiting the same area at the same time.
It lived in the Sahara and also possibly South America too (fragmentary remains ofsomething very similar).I suppose that Sarcosuchus is the biggest ever crocodilian we know about?
Had a feeling you might ask that
Well Sarcosuchus and Mourasuchus (which lived in South America during the Miocene after the dinosaurs died out) were both about 40 feet long. Mourasuchus was an odd one as it's head was not lik that of a typical crocodilian. It appears to have been a filter feeder.
Mourasuchus shared it's habitat with two other giant crocodilians; Gryposuchus, which resembled a ten meter long gharial, and the mighty Purussaurus, which was arguably the biggest, exceeding 40 feet.

Well, the Miocene sea was home to one of the most awesome marine predators of all time, the megalodon and the Brygmophyseter, a smaller toothier relative of the sperm whale..
The megalodon (at least 50 feet long) and the Brygmophyseter (40 feet long max.), probably never encountered these giant crocs though, as the crocs do not appear to have lived in a marine environment.
Just for fun:

I just noticed it's referred to as Carcharodon megalodon in that picture. That name is heavily disputed. Last time I checked the majority of experts sided with the name Carcharocles megalodon. That is why most writers like to simplify with either C. megalodon or just megalodon.0 -

I have only ever called it Megalodon myself. Everyone knows what you mean by that. Same as T rex, not many call it Tyrannosaurus rex.
T rex, T smecks, gimmie back my Dynamosaurus.

That never really existed did it?
I thought and I may be wrong here that it was just a T rex with another armoured skeleton on top of it.
I am not sure though, but it seems to tug at my memory strings that that is what it was.
I am going to try to find out now...... damn you for stirring up ancient memories
