Here is a Magister Militum Giganotosaurus from their 10mm dinosaur range. The real monster lived in South America about 97 million years ago and is one of the largest carnosaurs ever discovered. Though designed for use with 10mm-1/160th figures, the Magister Militum figure still looks good with 15mm humans. The model is 8cm long which would make it about 26 feet at 1/100th. Not a giant by any means, but still a sizeable predator. In fact it is only slightly smaller than the 15mm Primaeval Designs Tyrannosaur, which is about 9cm long(30′).
