The Most Massive Dinosaur, and Are Earthquakes Contagious?

The video discusses the discovery of Dreadnoughtus, the most massive dinosaur ever measured, found in Argentina. It highlights the significance of having both femur and humerus bones intact, allowing accurate mass estimation. The video also explores the unrelated nature of earthquakes occurring around the same time in different locations, emphasizing the constant seismic activity on Earth and the challenges in finding connections among them.

What is the significance of the Dreadnoughtus discovery?

• It is the first dinosaur found in Antarctica.

• It is the most massive land animal with accurately calculated body mass.

• It is the smallest dinosaur ever discovered.

• It is the first dinosaur discovered in the 21st century.

Why is Dreadnoughtus considered a significant find compared to other titanosaurs?

• It was found in a volcanic region.

• It is the only dinosaur with feathers.

• It was discovered in North America.

• It was found with both femur and humerus intact.

How does the completeness of Dreadnoughtus fossils benefit scientific research?

• It shows dinosaurs lived in water.

• It indicates dinosaurs were nocturnal.

• It proves dinosaurs could fly.

• It allows for accurate mass estimation and further studies on anatomy.

What is the common misconception about earthquakes?

• They are caused by volcanic eruptions.

• They are contagious and can trigger each other globally.

• They only occur in the daytime.

• They are always followed by tsunamis.

Where do most earthquakes occur globally?

• In the Arctic Circle

• Around the Ring of Fire

• In the Sahara Desert

• In the Amazon Rainforest
