Some Herbivores grazed everything that grew during the time carnivores, like Allosaurus, or the super famous veloci- of the dinosaurs. Depending on the type of dinosaur, raptors, hunted in packs and used numbers to over- everything from low lying scrub and bushes, ferns, etc.. whelm prey species many times larger than them- all the way to the tallest conifer trees. Some herbivores, selves. like sauropods, were of immense size.

Carnivores Vs. Herbivores

About this craft: Stomp into this craft to make a pair of Dino feet and learn about the differences between Carnivorous and Herbivorous dinosaurs!!

Recommended Ages: 6-11

SUPPLIES:

 Green Craft foam, 2 sheets  Dino Foot templates  Glue per person  Scissors  Round sequins  White construction paper, 3”  Crayons x 6”  Feathers

INSTRUCTIONS:

1. Choose whether you would like a herbivore foot or carnivore foot. Cut out the template. Fold the foot in half lengthwise to cut out the foot insert part. 2. Trace the foot twice on the green craft foam paper with a marker. Cut out the feet and foot insert. 3. Cut out toe nails from the white construction paper and glue them on the toes of the feet. 4. Color the feet and toe nails (if desired) with markers. Decorate the feet with feathers and sequins. If you are a carnivore, use glue on feathers as carnivorous dinosaurs are a direct relative to birds. If you are a herbivore, glue on sequins. Sequins will closely resemble dinosaur skin and scales as these dino- saurs were more closely related to modern day reptiles. 5. When you are finished decorating, slowly and carefully slide your foot in the foot insert of each foot. Stomp around with your new dinosaur feet! Herbivore Foot Template
