Okay to the Spinosaurus weighs 23 tons.
According to Fan, the fastest bird has around 169 kilometers per our in swooping speed (AKA Short burst movements/flight)
Put that into a KE calc, and we get 22991120.710282337 Joules. Room Level.
Finally.
To quote Fan directly:
"a composite therapod can fly up to 169 km/hr, swim up to 40 km/hr, use tools, is as big as a spinosaurus, has the bite of a Trex, can survive antarctic temperatures, has the intellegence of Corvidae birds, and can swim under 535 meters"
And it would supposedly have a wingspan this big

And would have the eyesight of a hawk, which seems to be able to sense ultraviolet light, and possesses nocturnal vision, as well as 10x better eyesight than humans
and claws as big as a ruler
So basically to summarize, the composite therapod would be Ultimate Kars.
Still though, may not be
quite as versatile as the composite fish. xD
