名字的意思： “named after the La Bocana Roja Formation, which means 'the red estuary'”1

吃：肉暴龍類白堊紀晚期

Labocania was a meat-eating dinosaur that lived in Mexico during the Late Cretaceous, about 85 to 72 million years ago. It was a medium-sized predator with strong bones and sharp teeth. Scientists are still figuring out exactly what kind of theropod it was.1 2

酷東西

趣味知識

Labocania's skull bones were very thick and strong, especially the bones on top of its head.1

The first Labocania fossils were found in 1970 by a volunteer named Harley J. Garbani during an expedition in Baja California, Mexico.1

Labocania's teeth were flat and curved backwards, which helped it hold onto prey.1

Scientists have debated whether Labocania was a tyrannosaur, an abelisaur, or a carcharodontosaur. In 2024, a new study placed it with tyrannosaurs.1

The second species, Labocania aguillonae, was named in 2024 after Martha C. Aguillon, a paleontologist from Coahuila, Mexico.1

Labocania lived on land and walked on two legs, like other theropods.2

關於 Labocania 最常被問的問題

?How big was Labocania?

Labocania was a medium sized carnivore. The species L. anomala was about 7 to 8.2 metres long and weighed around 1.5 to 2.6 tonnes. The smaller L. aguillonae was about 6.3 metres long.1

?Is Labocania a dinosaur?

Yes, Labocania is a dinosaur. It is a theropod dinosaur that lived in Mexico during the Late Cretaceous.1

?What did Labocania eat?

Labocania was a meat-eater. It had sharp, curved teeth and strong bones to help it catch and eat other animals.1

?When did Labocania live?

Labocania lived during the Late Cretaceous period, about 85 to 72 million years ago. Some estimates suggest it might have lived as early as about 93.6 million years ago.1

?Was Labocania a tyrannosaur?

Scientists have debated this, but a 2024 study found that Labocania was a tyrannosaur, specifically a member of the group Teratophoneini. Earlier studies had suggested it might be an abelisaur or carcharodontosaur.1 3

?Where was Labocania found?

Labocania fossils have been found in Mexico. The first species, L. anomala, was found in Baja California, and the second, L. aguillonae, was found in Coahuila.1 4

迷思破解王

迷思： Some people think Labocania was definitely a tyrannosaur like T. rex.

真相： Scientists are not sure. It might be a tyrannosaur, but some studies suggest it could be an abelisaur or a carcharodontosaur. The most recent study in 2024 supports tyrannosaur, but others disagree.1
