Кентрозавр - род стегозаврид из поздней юры Танзании. Достигал 4,5 м. Kentrosaurus is a genus of stegosaurid dinosaur from the Late Jurassic of Tanzania. Its fossils have been found only in the Tendaguru Formation of Tanzania, dated to the Kimmeridgian stage, between about 155.7 ± 4 Ma and 150.8 ± 4 Ma (million years ago). Apparently, all finds belong to one species, K. aethiopicus Hennig 1915.
Kentrosaurus was described by German palaeontologist Edwin Hennig in 1915. Often thought to be a primitive member of the Stegosauria, several recent cladistic analyses find it to be derived, and a close relative to Stegosaurus from the North American Morrison Formation.
Kentrosaurus generally measured around 4.5 metres (15 ft) in length as an adult, probably had a double row of small plates and spikes running down its back, and could use its tail as a "thagomizer" for defense. The femora (thigh bones) are strongly dimorphic, suggesting that one gender (likely the females) was larger and more stout than the other.
