Question 1

How do you say Aegyptosaurus?

Accepted Answer

You say it ee-JIP-toe-SORE-us. The trickiest part is the start because the ae makes an ee sound, just like in the word aegis. A great memory trick is to say the word Egypt out loud, then add toe-SORE-us right after it. That is basically the whole name. The Natural History Museum in London confirms this pronunciation is the standard one used by paleontologists worldwide.

Question 2

What does Aegyptosaurus mean?

Accepted Answer

Aegyptosaurus means Egypt lizard. The first part of the name comes from the ancient Greek word Aegyptos, which is what the Greeks called Egypt, and the second part comes from sauros, the Greek word for lizard. German paleontologist Ernst Stromer chose this name in 1932 because the fossils were discovered in Egypt's Bahariya Oasis. The species name baharijensis is also named after Bahariya, the specific oasis where the bones were found.

Question 3

How big was Aegyptosaurus?

Accepted Answer

Aegyptosaurus was enormous, reaching about 52 feet long, which is roughly the length of three school buses parked bumper to bumper. It weighed an estimated 40,000 pounds, which is heavier than three adult African elephants standing together. It belonged to the titanosaurs, the largest group of dinosaurs that ever lived, and was one of the biggest animals in its African ecosystem. Despite its huge size, its head was tiny relative to its body, a common trait in sauropod dinosaurs.

Question 4

What did Aegyptosaurus eat?

Accepted Answer

Aegyptosaurus was a herbivore, meaning it ate only plants. It used its long neck to reach the tops of tall conifers and other trees, stripping away leaves and branches. Like all sauropods, it could not chew and instead swallowed plant material whole, relying on its massive stomach to slowly digest everything. Scientists estimate that an animal this large would have needed to eat hundreds of pounds of vegetation every single day just to survive.

Question 5

Where did Aegyptosaurus live?

Accepted Answer

Aegyptosaurus lived in what is now Egypt in North Africa, specifically in a region called the Bahariya Oasis, which today is a remote desert about 370 kilometers southwest of Cairo. But 95 million years ago it was a completely different place, a lush tropical wetland full of rivers, mangrove swamps, and dense forests right next to a warm shallow sea. The Sahara Desert did not exist yet. Aegyptosaurus shared this rich, swampy ecosystem with Spinosaurus, Carcharodontosaurus, and giant crocodile relatives.

Question 6

Are the Aegyptosaurus fossils real, or were they destroyed?

Accepted Answer

The original Aegyptosaurus fossils really were destroyed. On the night of April 24 to 25, 1944, Allied bombing raids hit the museum building in Munich, Germany, where Ernst Stromer had stored all the bones he collected from Egypt. The fossils were lost in the fire that followed. Fortunately, Stromer had published detailed scientific descriptions, drawings, and measurements before the war, so scientists still know what the bones looked like. New expeditions to the Bahariya Formation, including Josh Smith's 2001 trip, have found additional titanosaur material from the same area.

Question 7

What other dinosaurs lived with Aegyptosaurus?

Accepted Answer

Aegyptosaurus lived in one of the most dangerous dinosaur neighborhoods ever discovered. Its ecosystem in the Bahariya Formation included Spinosaurus, a massive sail-backed predator that was longer than T. rex and hunted fish in rivers. Carcharodontosaurus, a giant meat-eater with serrated shark-like teeth, also prowled the same forests. The enormous crocodilian Sarcosuchus, sometimes called SuperCroc, lurked in the waterways. For Aegyptosaurus, growing as large as possible as fast as possible was probably the best survival strategy available.

Question 8

Who discovered Aegyptosaurus?

Accepted Answer

Aegyptosaurus was discovered by Ernst Stromer von Reichenbach, a German paleontologist and Bavarian nobleman, who led expeditions to Egypt between 1911 and 1914. He formally named and described the dinosaur in a 1932 scientific paper. Stromer's story is a tragic one because he was a known opponent of the Nazi regime, and Nazi authorities refused his repeated requests to move his irreplaceable fossil collection to safety during World War II. The collection was destroyed in the 1944 bombing, and Stromer died in 1952 knowing his life's greatest scientific work had been lost.
