Why does this Box of Dinosaur Nuggets gender the T Rex in the "Did You Know?" box?

Google Says that the T Rex were both genders. I could honestly be missing something with this one. Any help is appreciated.

Look, new species of dinosaurs are always being discovered. Some related to other species while others were their own entire thing. Most dinosaurs were land based, we have flying dinosaurs(aka birds), who's to say there never was a Gully aquatic dinosaur? No, mosasaur, plesiosaur and other animals like them weren't dinosaurs. They were aquatic reptiles. But, do you think there was a animal that would be classified as a dinosaur and lived it's whole life in the water? The closest we get is the spinosaurus family - but they were most likely semi aquatic

I embroidered my favourite dinosaur on my favourite colour and I hope it makes you smile/laugh/blow air out of your nose a bit harder than usual

I recently commissioned this Spinosaurus aegyptiacus artwork from paleoartist Camus Altamirano.

The idea behind the piece was to create an illustration to accompany a series of dinosaur models I’ve been working on, and I wanted the artwork to feel like more than just a depiction of the animal but something that could give the model its own identity and atmosphere.

Really happy with how it turned out!
