The species, which lived 233 million years ago in the region of what is now S\u00e3o Jo\u00e3o do Pol\u00easine in Rio Grande do Sul, is considered to be the most primitive of the sauropodomorpha, although its anatomy is quite different to other species in this lineage, composed mainly of four-legged herbivorous giants with long necks, such as the brachiosaurus and diplodocus. <em>B. schultzi<\/em> was small, bipedal, and carnivorous. It was about 0.5 meters (m) tall and 1.5 m long, weighing in at 6 kilograms. But its cognitive ability seems to have been greater than that of the large sauropods that emerged 100 million years later (<em>Journal of Anatomy<\/em>, November 3). In proportion to its body weight, its brain was larger than later sauropods. \u201cThis is an intriguing fact, since in many vertebrate lineages, brain size tends to increase over time, not decrease,\u201d says paleontologist Rodrigo T. M\u00fcller of the Federal University of Santa Maria (UFSM), the study&#8217;s lead author. Brain structures linked to vision were also more developed in <em>B. schultzi<\/em> than in other sauropods, particularly the olfactory bulb.<\/p>\n<div id=\"attachment_385337\" style=\"max-width: 1910px\" class=\"wp-caption aligncenter\"><a href=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2021\/02\/012-017_Notas_298-0-img.png\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-385337 size-full\" src=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2021\/02\/012-017_Notas_298-0-img.png\" alt=\"\" width=\"1900\" height=\"700\" srcset=\"https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2021\/02\/012-017_Notas_298-0-img.png 1900w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2021\/02\/012-017_Notas_298-0-img-250x92.png 250w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2021\/02\/012-017_Notas_298-0-img-700x258.png 700w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2021\/02\/012-017_Notas_298-0-img-1536x566.png 1536w, https:\/\/revistapesquisa.fapesp.br\/wp-content\/uploads\/2021\/02\/012-017_Notas_298-0-img-120x44.png 120w\" sizes=\"auto, (max-width: 1900px) 100vw, 1900px\" \/><p class=\"wp-caption-text\"><span class=\"media-credits-inline\">M\u00e1rcio L.
