During the last decades, studies testing the correlations between the dynamics of diversity with various environmental variables strongly increased, but numerous biases affecting these analyses have been recognised. Recent studies considering the evolution of marine crocodylomorphs in comparison with the fluctuations of sea surface temperature and sea level found contradictory results. However, we considered a diversity analysis published two years before our work, and noticed several taxonomical issues (new material and species described since the publication of this paper, unidentified thalattosuchians in time bins where previous analyses considered the absence of any marine crocodylomorphs, and some taxonomical corrections). Here we test the impact of updating the dataset on these results. We also tested the consequences of the time range considered and various methods in reconstructing the sea surface temperature curve. Each of these corrections and modifications impacts strongly the results and most of them drive to a different conclusion from the original work. These results points out the crucial importance of taxonomical work in diversity studies to provide reliable results, such as the method used to construct the proxies. The contradictory results obtained here question the reliability of the correlations proposed until now between crocodylomorph evolution and environmental proxies. Deep taxonomic and phylogenetic review should be conducted prior to study the diversity evolution of a group. This also strongly questions the use of the Paleobiology Database in diversity analyses when the studied group has not yet been reviewed and that numerous, doubtful, 18th century species are considered in this dataset.

En este trabajo analizamos el papel que se le otorga a la educación patrimonial en los museos histórico-artísticos, de la ciencia y parques naturales. Trabajamos con los materiales didácticos editados por los centros patrimoniales con mayor número de visitas en el ámbito español en cada categoría. El objetivo consiste en caracterizar la perspectiva patrimonial transmitida por estos materiales, detectar las dificultades y obstáculos existentes respecto a la educación patrimonial y realizar aportaciones que permitan su integración desde una perspectiva transdisciplinar, constructivista y socio-crítica. Para ello se elaboran diferentes instrumentos de obtención y análisis de información (hipótesis de progresión, hojas de observación y recogida de datos y tablas de categorías) que permiten el estudio sistemático y riguroso de los materiales y centros patrimoniales objeto de investigación. Los resultados, en general, ponen de manifiesto el uso del patrimonio como recurso educativo y las relaciones existentes entre los diferentes tipos y centros patrimoniales para desarrollar propuestas educativas coherentes con las líneas de trabajo que se establecen. Palabras clave: Educación Patrimonial; museos, parque nacionales, materiales educativos Abstract The role of Heritage Education is analysed through the historical, artistic, science museums and natural parks. We work with educational documents edited by the most visited heritage centres in each typology in Spain. The aim is to characterise the patrimonial outlook transmitted by these materials, detect the difficulties and obstacles in terms of heritage education and provide input to allow integration from a transdisciplinary, constructivist and socio-critical perspective. To this end, different research instrument are developed (progression hypothesis, observation sheets and data collection categories and tables) to enable a systematic and rigorous analysis of the educational materials and centres studied. The outcomes, in general, allow us highlighting the disciplinary use of heritage as an educational resource, and its relationships between several heritage centres and typologies with our educational proposals.
