Resumo
Embora o grupo dos dinossauros sauropodomorfos seja amplamente conhecido em virtude dos gigantescos saurópodes, sua origem ainda é pouco compreendida em virtude da escassez de esqueletos completos ou datações precisas. Entretanto, novos achados e datações realizadas em rochas Triássicas do Brasil têm trazido à tona informações valiosas no que tange essa questão. A combinação desses novos dados com técnicas mais avançadas de investigação (e.g. tomografias computadorizadas) vem possibilitando o estabelecimento dos padrões macroevolutivos que direcionaram a evolução inicial do grupo. Por meio das descobertas realizadas nos leitos Triássicos do Rio Grande do Sul, podemos entender de forma mais refinada de que forma os sauropodomorfos passaram de animais pequenos e pouco abundantes aos maiores animais que já andaram sobre a Terra.
