B. Measure the height of dinosaur replicas

1. If the animal has all four legs on the ground you have two options for measuring height:

a. Measure height from the ground to the top of the head.

b. Measure height from the ground to the top of the hind hip.

2. If the animal has only two legs on the ground, measure height from the ground to the top of its head.

3. Record measurements in the Table of Cretaceous Critter Calculations. Be sure to record the unit of measurement.

C. Measure the width of dinosaur replicas.

1. Measure the greatest width of the replica with the string.

2. Record measurements on the Table of Cretaceous Critter Calculations. Be sure to record the unit of measurement.

D. Measure the weight of dinosaur replicas.
Many dinosaur replicas are made from a flexible plastic that’s nearly the same density as animal flash. This makes it possible to make a reasonable estimate of the real-life weight of the dinosaur. Individual dinosaurs of the same species would vary in weight so there is some margin for error.

1. Weigh the replicas on a scale in pounds or grams.

2. Record the weights on the Table of Cretaceous Critter Calculations. Be sure to record the unit of weight.
