As it turns out, it has been thypothesized that orca whales played a part in the downfall of the megalodon, out-competing and possibly predating upon their young.

A Tv documentary recently put forward that there was a large toothed whale that hunted Megalodon in packs. Not an Orca but an earlier version. I can't remember the name of the creature I am afraid, but I know one of you will have heard of it.

Brygmophyseter? - a cousin of the sperm whale.

From Jurassic Fight Club >.< Bad show...

There is also Leviathan (yeah, I know about the new spelling but I don´t really like it XD)

Galvasean

Yeah that paleontologist / interviewee guy they have on it is quite the head wrecker.

Or this...



Small shark, tho. BTW what an amazing Dunkleosteus pic John Sibbick, N'est-ce pas?

Galvasean

mmmm shark

Adam Khor

Or this... scavenging but shark-eating at the end of the day. I have a better pic of a hyena eating a shark in my computer but, I think you can´t upload directly from your hard drive to the forum?

supposedly 2m long - so it's about the right size for a person
will look up the book later on

forget T-Rex - Dunkleosteus hd biggest teeth ever ?

Galvasean

That Livyatan whale is supposed to have had the biggest teeth ever...

It didn´t have teeth, I think those scissor like things were modified jaw bones : >

Arf!

The big Dunk is really just a tiddler you know.

I think some of those shark eating fish may have been this fella too:

I know , but for it's time it was a monster
and it still has wicked choppers

Rubecula

As soon as I get my printer fixed I would like a copy of that.

Thank you very much Cap'n.

Some serious messing about with sizes going on in that pic if they are meant to be somewhat to scale.

Leedsichthys looks in the 80 foot range in that pic. All recent studies on it have put it in the 30 - 35 foot range with a few saying it may have had a maximum size of 50-55 foot.


The Archelon in the pic looks to be three or four times longer than the human, but the largest ever fossil remains were from a specimen estimated to be about 13 foot long.

The pic is from Tim Haines' Chased by Sea Monsters, which is from the same "litter" as Walking with Dinosaurs. I have the Walking with Dinosaurs book and it explains how the series creators would often base their creatures on undescribed and fragmentary remains. For example, Stegosaurus is officially "only" 9 meters long but there were fragmentary remains found in the US that suggested that larger individuals, probably up to 12 meters long, had existed. So of course they embraced this maximum estimate. They did the same with Diplodocus, Ankylosaurus and Ornithocheirus, and more famously with Liopleurodon.
So I wouldn´t be surprised if this was their modus operandi with Chased by Sea Monsters as well.
Even so I don´t think the pic is all to scale; the Xiphactinus looks almost as long as the Elasmosaurus and the "Megalodon"...

Because nobody has ever found a complete Leedsichthys skeleton, it’s not clear how big, exactly, Leedsichthys Problematicus grew. Modern estimates put it at 50 to 75 feet long (16 to 22 metres), making it the biggest fish ever – bigger than the Whale Shark or the Megalodon ! Not everyone agrees, however

Galvasean

The Xiphactinus is way too big. He could swallow a human like a pea!

Those estimates are based on old research. Pretty much all research since 2003 has them in the 30-25 foot range with the possibility of a few 50-55 foot outsized specimens. The 60, 70, and 80 foot estimates have long since been discounted and put down to overestimation and incorrect scaling up from fossil finds.

Rubecula

To be honest I think that poster is one of those things they pin up in a school for science class. None of the sizes look right really.

Thanks for the info Kess.

280 million years ago back in the Permian there was mesosarus it looked like a croc so it may have gobbled the odd shark too

how long have remoras been around ?

I think the oldest are from the Eocene. Could be wrong tho...

That looks a lot like the 'Walking With...' series.
Wonder where they put the Liplurodon. Probably on the back because apparently it was freekin enormongus (yes. that is a word):D

Adam Khor

I'm telling you, the pic is from Chased by Sea Monsters, a Walking with Dinosaurs special. I have it on DVD

I guess a modern version would include Leviathan (I like the original spelling, ok?) probably fighting Megalodon. Now that fight I would like to see, unlike those stupid Animal Face Off-ish fights in History Channel...

BTW I found the other pic of the hyena scavenging a shark. (A big one, too).

Crocs being eaten...

The crocodile in the first pics wasn´t eaten, it was just killed If I well remember...
As for the one in the last pic, its a caiman not a crocodile, but I assume we're talking about crocodilians in general. :>

Here are some more.
Leopard vs Nile crocodile:



Jaguar vs caiman:



Tiger vs Mugger crocodile:





Seems that big cats usually have the upper hand over crocodilians... jaguars and tigers have even been known to kill them on the water (were crocs are most dangerous) and drag them to land to devour them.

Also, here's the uber-famous pic of the python that "exploded" after eating an American Alligator:



Saltwater croc eaten by another saltwater croc:



And finally, the famous pics of the "lionesses vs crocodile" battle, which the poor croc lost at the end:

Rubecula

I seem to remeber a tv documentary that showed a single croc chasing away a whole pride of lions from a kill.

It must depend on the size of the croc and how hungry/desperate the combatants are at the time.

Galvasean

I remember that one too. In fairness, he was one HUGE croc.

I know this is art, but cool!

Capt'n Midnight

Another croc



(probably Nile perch or similar)

Adam Khor

Monstrous; If I found something like that in my canned fish I would probably go vegetarian XD

Could it be perhaps a Goliath tigerfish? That fish has monstrous teeth and is said to attack Nile crocodiles:

Galvasean

^^ scary monster :eek:

Not sure if this has been posted already, but:



This pic is based on fossils of crocodile dung that have shark tooth marks on them, which were seemingly made when the dung was still inside the crocodile (that is, the shark bit the crocodile and punctured its guts and the dung inside). The shark was a relative to tiger sharks.

Rubecula

Good grief!

Galvasean

Anyone see these photos of a leopard fighting a croc?

According to QI hippos drag sharks out of the water and then trample them to death

I think I posted some of those in a previous post. More proof that no one reads my posts!! Haha JK
