T-Rex was smart and could count to 10, according to David Attenborough

T-REX was smarter than people think, according to David Attenborough.

The scary dinosaur was able to count — as it knew if eggs were missing from its nest.

It was also cunningly quiet when hunting, not crashing noisily through trees as is often portrayed in movies.

TV wildlife presenter Sir David, 96, bigs up the much-maligned predator in his new Prehistoric Planet series.

He said: “The T-Rex could count to ten to check that all its eggs were in the nest.” 

Paleontologist Dr Darren Naish said the claim was backed by research into its living relatives.

He told The Sun: “It’s been shown lizards can count. It’s been shown birds can count.

“So we’ve got every reason for thinking this would be present in extinct dinosaurs like the T-Rex.

“Most dinosaurs produce large clutches of eggs.

“If you have a large number you need to keep track.” 

It means the T-Rex may be as smart as the “clever girl” raptor hunted by Muldoon in 1993’s Jurassic Park.

Dr Naish also says the predator could make a right romantic racket — with its gob shut. He said: “It made a deep booming noise with its jaws closed when mating.”

The series uses CGI to go back 65million years. An episode will stream each day this week on Apple TV+.
