Resumo: Tijubina pontei is a basal lizard found in the Crato Member, Santana Formation, Lower Cretaceous (Aptian), Brazil. It is considered a sister group of Huehuecuetzpalli mixtetus, the only basal lizard previously known, found in Mexico. The paleoautoecology of T. pontei is compatible with a terrestrial animal, omnivorous, which could eventually occupy other ecological niches. Based on their dentition and ecomorphology, their behaviour could be a combination of active forager or a "sit-and-wait" one. It could even perform bipedal locomotion. Comparing T. pontei with Liolaemus lutzae, an extant brazilian lizard, we find many characters and morphological similarities. This suggests that the L. lutzae habits could be extrapolated to the paleoenvironment of T. pontei which, probably, lived in a sandy habitat, with a vegetation that could support variations in salinity and high temperatures.

A paleoautoecologia de T. pontei é compatível com a de um animal terrestre, onívoro que, eventualmente, pudesse ocupar outros nichos ecológicos. Baseado em sua dentição e ecomorfologia, seu comportamento poderia ser combinado, como forrageador ativo ou senta-espera, podendo apresentar bípedalismo. Comparando-se T. pontei com Liolaemus lutzae, lagarto atual do Brasil, encontramos muitos caracteres e inúmeras similaridades morfológicas entre ambos, sugerindo que os hábitos de L. lutzae, poderiam ser extrapolados para o paleoambiente de T. pontei que, provavelmente, vivia em um ambiente arenoso, praial, com uma vegetação que poderia suportar variações de salinidade e de altas temperaturas.Universidade Federal do Rio de Janeiro2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/661710.11137/2006_2_54-65Anuário do Instituto de Geociências; Vol 29, No 2 (2006); 54-65Anuário do Instituto de Geociências; Vol 29, No 2 (2006); 54-651982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/6617/5214Copyright (c) 2006 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBonfim-Júnior, Francisco de CastroRocha-Barbosa, Oscar2022-10-17T14:41:25Zoai:www.revistas.ufrj.br:article/6617Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2022-10-17T14:41:25Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false
