How big were dinosaurs? Scientists in Scotland found dinosaur footprints and think they were made by a Cetiosaurus. This dinosaur was about 50 feet long and weighed more than 12 tons, as much as 2-3 elephants.! Just to picture this, look at your thigh, the part of your leg from your hip to your knee. That one leg bone on Cetiosaurus was 6 feet tall, taller than a lot of grownups!

*Wee ones*: If you see 9 dinosaur footprints, what numbers do you say to count them?

*Little kids*: How much taller than you would a dinosaur’s 6-foot leg bone be? (You can round your height to the nearest foot.) *Bonus*: How many Cetiosauri with all 4 feet on the ground could have filled 12 of those footprints?

*Big kids*: If that dinosaur is 50 feet long, and half of that length is its tail, how long is its tail? *Bonus*: Who weighs more, a 12-ton Cetiosaurus or a 20,000-pound truck? (Hint if needed: A ton equals 2,000 pounds.)

Answers:

*Wee ones*: 1, 2, 3, 4, 5, 6, 7, 8 ,9.

*Little kids*: Different for everyone…subtract your height in feet from 6. *Bonus*: 3 Cetiosauri.

*Big kids*: 25 feet. *Bonus*: The Cetiosaurus, since it weighed 24,000 pounds!
