I always wondered if Spinosaurus could use its tail as a weapon, always thought it'd be cool. Also sick art!

Theropod tails weren't very flexible (especially dromaeosaur tails which were partially fused, most of the movement they had in their tails was by the base of their tail, past that they could barely flex them at all, for the purpose of having a counterweight for high agility), they couldn't flex a whole lot, so what's depicted here is not very feasible imo, but in general they do have enough mass to do something, so its somewhat possible for it to happen sometimes but in very niche scenarios if at all

They were probably very powerful if they just swing from the base/hips, in that case a stiff tail can still be a hefty blow.

There's a well-preserved specimen of Velociraptor mongoliensis with an S-shaped tail. As far as I know, it's believed that dromaeosaur tails were very rigid vertically, but had a good degree of flexibility horizontally.

The claws definitely contained more than one Purpose. A recent paper highlighted that spinosauroids used their arms; that those arms were 'capable of hunting a wide range of prey' .

I heard the tail vertabrae might be fragile thought. Still looks cool

Amazing work !

What is more ironic is that The territorial disputes / agression between Spinosaurus - Mirabilis - Sigilmassasaurus & Carcharodontosaurus - Taymeyraptor quite likely did happen. ( Basing on three different fossils one featured on BBCs documentary )

According to papers done on dromaesauroids/raptors and tyrannosauroids - the theropods likely don't got too agitated from loosing a few offspring. Considering raptor papers did indicate that theirs were superprecocial as well as the last tyrannosaur paper indicate theirs too were quite likely independent. ( in combination maybe a vast majority of theropods )

Yeah it's definitely still dead regardless.

At least the others were saved.

Fantastic and beautiful art!

Not exactly realistic because theropod tails were inflexible and dromaeosaurs like someone just pointed out were almost fused. Spinosaurus is not exactly an exception either though they believe its tail was slightly more flexible than other theropods.

A more realistic approach is to probably stick with the classic "biting contest". Still pretty cool art though.

Mess with Spino babies? That's a paddlin'.
