This is a professional, museum-quality reproduction cast of the Berlin specimen of Archaeopteryx lithographica. This was the world's first known bird fossil. It was found in Jurassic (145 mya) limestone in Solnhofen, Germany in 1877. This bird had teeth in its jaws instead of a horny beak like modern birds. This cast measures 19" (48.26 cm) x 15" (38.1 cm) wide.
This is a professional, museum-quality reproduction cast of the Eichstaat specimen of Archaeopteryx lithographica. This specimen was discovered in 1951 in the Jurassic (145 mya) Solnhofen lithographic limestone in Germany. This specimen is about 2/3 the size of the famous Berlin specimen found in 1877 and is believed to be a juvenile.
This is a profesionally made, museum-quality reproduction cast of an egg of, possibly Saurolophus (a large, herbivorous dinosaur), from the Cretaceous of Henan Province in China. This fine quality cast measures 9" (22.86 cm) long.
This is a kit of biological specimens that can be used for dissection or as displays. Each specimen is packed in a reclosable plastic bag and the bags are inside another reclosable plastic bag and packed into an 8" x 6.5" x 6.5" (tall) Sterilite box. The box has a snap-shut lid with a handle for carrying.
Each kit contains one each of the following specimens: crayfish (4"-6"), earthworm (9"-12"), freshwater mussel (clam) (4"-5"), leoparf frog (4-4.5"), yellow perch (7"-9") and starfish (5"-6").
