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

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

The creepy dinosaur could count – knowing if eggs were missing from its nest.

He was also cleverly quiet when hunting and didn’t crash loudly through trees, as is often portrayed in films.

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

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

The paleontologist Dr. Darren Naish said the claim is supported by research done by his living relatives.

He told The Sun: “It has been shown that lizards can count. It has been shown that birds can count.

“So we have every reason to believe that this might be present in extinct dinosaurs like the T-Rex.

“Most dinosaurs produce large clutches of eggs.

“When you have a large number, you need to keep track of them.”

That means the T-Rex might be as smart as the “smart girl” raptor hunted by Muldoon in Jurassic Park in 1993.

dr Naish also says the predator could make a proper romantic noise — with its mouth closed. He said, “It made a deep booming sound when mating with closed jaws.”

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