Can someone shed a little light on just how big Titanosaurus was? Different sources are giving me different answers. Thanks.

I have no clue, Titanosaurus is something of a wastebasket taxon if I recall correctly.

Ya, as are "ultrasaurus". and "supersaurus" too, it seems. Every big thigh bone they find becomes "ultimatosaurus" or some such.

Titanosaurus is pretty strange case. It was originally named just based on 2 tail vertebrae. And they're not even that big either, the biggest is just a little over 10cm long.
A lot of bones have been referred to Titanosaurus since then, but most of that is quite dubious. I think the idea was any scrappy late Cretaceous sauropod was Titanosaurus. I don't know if there's anything other than the original 2 vertebrae that can truly be called Titanosaurus.
Titanosaurs, on the other hand, we've learned quite a bit about in the past number of years. That's the whole family of sauropods that share characteristics with those 2 original Titanosaurus vertebrae. It includes the largest of all dinosaurs, like Argentinosaurus, but also some of the smallest of sauropods, such as Magyarosaurus.
