Didn't you post information in the profile of Basilosaurus suggesting that it could have amassed up to 20t? I have yet to read the full paper (because I'm busy with work) but it's probably too big for Spinosaurus, isn't it?

Yes the Basilosaurus does have that size advantage, but Spino still wins on land and shallow water. Not much at all Basilo can do, in fact the bigger the whale is the deeper the water it needs to win.

What do you expect a Spinosaurus to do to a potentially 20t cetacean even in shallow water (depending on how shallow is "shallow")?

It can bite and claw as much as it wants with little to no risk of retaliation.
Moreover, as is also the case in Spinosaurus vs killer whale, there is nothing the whale can do there, so Spino wins by default
By shallow, I mean 2-3 meters or so.

 I really wish I had something like a rigorous skeletal (made by a scientist), but for now I guess I'll have to make do with this reconstruction. Looking at the depth of its body, I'm under the impression Basilosaurus' body shape might actually allow it to have enough mobility to swim and maneuver in 3m deep water (even if obviously deeper water would benefit it). I don't think moving in yaw would be a problem, since it's the depth of the water that's comparatively limited not the area of the body of water. This is important because to retaliate the Basilosaurus would need to be able to turn in a lateral direction and bite back. |

I have yet to read the full paper (because I'm busy with work) but it's probably too big for Spinosaurus, isn't it? Yeah, it is. I got so hung up on the whole debate on shallow vs deep water and how well Spinosaurus could swim that I forgot what's really important. but so could Basilosaurus in shallow water (though on land, I agree with you). Exactly how shallow? Not sure. Maybe a little bit deeper than Basilosaurus' width but below Spinosaurus' height. And it can land a bite if Spino is careless, but I just don't see that happening short of freak incidents Think of it that way. Thanks to a size disparity so great that it almost renders further discussion unnecessary, Basilosaurus is going to survive very long in shallow water (if it even dies at all, in which case it's just a question of time until the freak incident takes place). In deep water, Spinosaurus will die immediately. |

In deep water, Spinosaurus will die immediately. 1: Sure, sounds good 2: There's a reason it's a FREAK. More often than not, Spino could win by default alone |

How does it win by default alone (which I presume means without Spinosaurus doing anything)? Do you think water of such depth is lethal to Basilosaurus? That it would crush under its own weight?
I don't think so. After all, it can move and keep its stomach above the sea floor, even if only barely. Basilosaurus doesn't even have to bite. Even a good hit with the tail could be enough to break Spino's bones (orcas can do this with seals).

Well yes, you do have a point.
But it's not going to be easy for Basilo to attack; it's still relatively stationary due to limited movement.
It may be a partial stalemate

Since Spinosaurus DOES have aquatic animal bone density and a big fin for a tail, this is valid after all!

I support the Basilosaurus due to its blubber, mobility, and more powerful jaws.
