All the Schleich figures are lovingly hand-painted with detailed modeling and allow kids to learn while they play. The Acrocanthosaurus was around the same size and weight as the Tyrannosaurus Rex and Giganotosaurus. Unlike many other dinosaurs, it had seven openings in its skull rather than five. It also had lots of neural spines on its neck, back and tail, which probably formed a small 'sail'. Schleich, founded in 1935, has been bringing figurines to life since the 1950's. In the 1980's, Schleich added animal figurines to their famous figurine line including the Smurfs, Snoopy, and the Muppet Show. Schleich animal play worlds span from the lost time of the dinosaurs to domestic and wild animals of the present day.Schleich play worlds now include the Wild West and the fantasy realms of medieval knights and elves. Schleich animal play worlds are a true reflection of nature on a smaller scale and are as realistic and naturalistic as possible!
