Pelagornis Sandersi: Flight and Discovery

In 2010, paleontologist Dan Sepa discovered the bones of Pelagornis Sandersi, the largest flying bird ever, in a Charleston museum. This bird had a wingspan of 24 feet and weighed only 48 pounds due to its hollow bones. Despite its size, it could fly using dynamic soaring, similar to the wandering albatross, by exploiting wind currents over the ocean. This allowed it to travel vast distances with minimal energy.

What significant discovery did Dan Sepa make in 2010?

• A new species of dinosaur

• The largest flying bird ever discovered

• A new type of reptile

• An ancient mammal fossil

How long was the wingspan of Pelagornis sandersi?

• 12 feet

• 24 feet

• 18 feet

• 30 feet

What feature of Pelagornis sandersi's bones contributed to its ability to fly?

• They were solid and dense

• They were hollow and thin

• They were short and thick

• They were flexible and rubbery

What does the small size of Pelagornis sandersi's scapula suggest about its flight?

• It was a powerful flapper

• It could not fly at all

• It flew only short distances

• It relied on gliding rather than flapping

Which modern bird's flight technique is similar to that of Pelagornis sandersi?

• Eagle

• Penguin

• Sparrow

• Wandering Albatross

What is dynamic soaring?

• A technique of flapping wings rapidly

• A method of using wind currents to gain altitude

• A way of diving into the water for prey

• A technique of flying in circles to confuse predators

How did Pelagornis sandersi manage to cover vast distances?

• By walking on water

• By swimming across the ocean

• By using dynamic soaring to catch faster air currents

• By flapping its wings continuously

Approximately how many years ago did Pelagornis sandersi live?

• 50 million years ago

• 10 million years ago

• 27 million years ago

• 100 million years ago

What type of environment did Pelagornis sandersi inhabit?

• Open sea

• Mountainous regions

• Dense forests

• Deserts

What was the primary advantage of Pelagornis sandersi's lightweight structure?

• It allowed for faster swimming

• It helped in hunting large prey

• It provided better camouflage

• It enabled long-distance flight with minimal energy
