A Dino Too Big for the Bed

March 30, 2016

There’s a new dinosaur in town, and it’s so huge it hardly fits in its house. A farmer in Argentina found some crazy-big bones in his field, and called in the paleontologists – scientists who dig up really, really old stuff. They named it the titanosaur since it’s so big: the thigh bone (top part of the leg) is 8 feet long! There were bones from 8 different titanosaur bodies, which they strung together to make one 122-foot-long skeleton. It’s so long that at the American Museum of Natural History, even with the body taking up two rooms, its tail sticks out the door a few feet. Not to mention that this dino stood about 46 feet tall, and the ceiling is only 19 feet high. It’s hard to tell from the size how much the titanosaur weighed: after all, a puppy weighs much more than a chicken the same size. But scientists guess that this giant weighed around 70 tons. Let’s be glad the skeleton weighs much less, or he’d fall right through the floor.

Wee ones: What numbers would you say to count the 8 titanosaurs?

Little kids: The titanosaur moved into the museum in January. If it’s now March, during how many calendar months has it “lived” in the museum?  Bonus: If the room were 120 feet long, how much tail would still stick out the door?

Big kids: If the 19-foot ceiling were made twice as high, would the 46-foot dino be able to stand up straight?  Bonus: The titanosaur is about 75 million years old! Can you “spell” that number in digits?




Wee ones: 1, 2, 3, 4, 5, 6, 7, 8.

Little kids: 3 months: January, February, March.  Bonus: Just 2 feet.

Big kids: Not quite! It would be only 38 feet, not enough for 46.  Bonus: 75,000,000.
