Resumo
Introdução. Dicinodontes são terápsidos herbívoros cosmopolitas com um extenso registro fóssil. No Brasil, esses animais foram encontrados em depósitos dos Períodos Permiano e Triássico localizados no Paraná e Rio Grande do Sul. Objetivo e Metodologia. Este estudo tem como objetivo revisar a diversidade taxonômica e a paleobiologia dos dicinodontes, com ênfase nos espécimes brasileiros, por meio da literatura publicada. Resultados. Os resultados revelam que os dicinodontes são um grupo diverso, com variações significativas em aspectos paleobiológicos, como tamanho e hábito de vida. Além disso, diferentes subgrupos apresentam níveis distintos de diversidade. Notavelmente, os dicinodontes brasileiros exibem uma assimetria na diversidade entre os períodos Permiano e Triássico. Essa disparidade pode sugerir uma diferença real na diversidade ou uma subestimação da mesma no Permiano, devido às limitações do registro fóssil atual. Conclusão. Portanto, estudos adicionais com os fósseis coletados no Brasil são necessários para investigar e compreender melhor essas questões.
