Without this mechanism, we might easily fall over while walking (e.g. hamstrings are pulling back while the quadriceps are pushing forward).
Answer:
Dimetrodon (/daɪˈmiːtrədɒn/ (About this soundlisten) or /daɪˈmɛtrədɒn/, meaning "two measures of teeth") is an extinct genus of non-mammalian synapsid that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Ma).It is a member of the family Sphenacodontidae. The most prominent feature of Dimetrodon is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, fossils have been found in Germany. Over a dozen species have been named since the genus was first erected in 1878.
