Completely dissolve gelatin in boiling water; cool, reserve 8 pear halves; dice remaining pears. Distribute diced pears evenly in bottom of 13x9x2 inch baking pan. Pour gelatin mixture over pears. Refrigerate at least 3 hours or until mixture is completely jelled. Dip bottom of pan in warm water 15 seconds, loosen gelatin and invert pan onto cutting board or cookie sheet. Cut with dinosaur shaped cookie cutters. Remove to individual plates with spatula. Garnish each with diced pear gelatin (leftover after cutting the shapes), pear halves and celery stalks.

Tips: Prepare several different flavors of gelatin for a colorful variety of pear Gelasaurs. Use celery stalks or carrots for trees and broccoli or cauliflower as bushes. Serve pear gelasaurs on a leaf or bed of shredded lettuce to creat a swamp.
