The Mystery of the Cleveland-Lloyd Dinosaur Death Trap

The video explores the Cleveland Lloyd dinosaur quarry, focusing on the mystery of why so many Allosaurus fossils are found there. Researchers suggest the site was a seasonal pond where dinosaur corpses were washed in by floods. The study also examines the tube lip wrasse, a fish with a unique feeding strategy on coral, using mucus-covered lips to protect against stinging cells. The findings provide insights into both prehistoric and modern ecosystems.

What is the main reason researchers believe the Cleveland Lloyd site became a boneyard?

• The site was a volcanic area that trapped dinosaurs.

• Predators hunted in packs and died together.

• It was a seasonal pond where corpses were washed in by floods.

• Dinosaurs migrated there to breed.

What did the geochemical analysis reveal about the heavy metals found at the Cleveland Lloyd site?

• They were evidence of a volcanic eruption.

• They likely originated from decaying dinosaur bodies.

• They came from the water being poisonous.

• They were deposited by ancient meteor showers.

What is the significance of the only egg found at the Cleveland Lloyd site?

• It belonged to a T-Rex.

• It was evidence of a new dinosaur species.

• It was fossilized in amber.

• It seems to belong to an Allosaurus, suggesting possible breeding.

What unique feature do the lips of the tube lip wrasse have?

• They are transparent and thin.

• They are covered in tiny teeth.

• They have deep folds filled with mucus.

• They are smooth and plain.

How does the tube lip wrasse's mucus help it feed on coral?

• It dissolves the coral skeleton.

• It acts as a chemical to attract prey.

• It changes the color of the coral to make it more visible.

• It forms a barrier against stinging cells and helps seal around the coral.
