    Abstract: El lenguaje de programación de código abierto ‘R’ se ha convertido en una herramienta común entre paleobiólogos. Su popularidad dentro de esta comunidad continúa creciendo, con cada vez más artículos que citan el uso de R y sus paquetes. Sin embargo, todavía faltan protocolos para la preparación de los datos, así como marcos de actuación para la aplicación de dichos protocolos. Por ello, los flujos de trabajo para la preparación de datos suelen resultar confusos y a menudo no reproducibles, incluso cuando se facilita el código. Además, debido a la falta de accesibilidad y documentación del código, los paleobiólogos se ven obligados frecuentemente a ‘reinventar la rueda’ para encontrar soluciones a problemas ya resueltos por otros miembros de la comunidad. Por este motivo presentamos palaeoverse , un paquete colaborativo de R para facilitar la preparación y exploración de datos en paleobiología cuantitativa. El paquete es de acceso libre y posee tres principios básicos: (1) agilizar la preparación y análisis de datos; (2) facilitar la lectura del código y (3) mejorar la reproducibilidad de los resultados. Para alcanzar estos objetivos, evaluamos las necesidades analíticas de la comunidad paleobiológica a través de una encuesta en línea, además de incorporar nuestras propias experiencias. En primer lugar, en el presente trabajo mostramos los resultados de la encuesta que determinaron el desarrollo de este paquete. A continuación, describimos y demostramos la funcionalidad disponible en palaeoverse, además de proporcionar ejemplos de utilización. Finalmente, discutimos los recursos disponibles para la comunidad y los planes futuros del proyecto palaeoverse. palaeoverse es un paquete colaborativo de R en paleobiología, desarrollado con la intención de unir a paleobiólogos y establecer normas consensuadas para una investigación cuantitativa de alta calidad. Este paquete proporciona una plataforma de fácil utilización para la preparación de datos para su análisis, con un código abierto bien documentado para aumentar la transparencia. La funcionalidad de palaeoverse mejora la reproducibilidad y accesibilidad del código, lo que es beneficioso tanto para el proceso de revisión como para futuras investigaciones.

    Abstract: Recently observed rates of environmental change are typically much higher than those inferred for the geological past. At the same time, the magnitudes of ancient changes were often substantially greater than those established in recent history. The most pertinent disparity, however, between recent and geological rates is the timespan over which the rates are measured, which typically differ by several orders of magnitude. Here we show that rates of marked temperature changes inferred from proxy data in Earth history scale with measurement timespan as an approximate power law across nearly six orders of magnitude (10 2 to 〉 10 7 years). This scaling reveals how climate signals measured in the geological record alias transient variability, even during the most pronounced climatic perturbations of the Phanerozoic. Our findings indicate that the true attainable pace of climate change on timescales of greatest societal relevance is underestimated in geological archives.

    Abstract: Paleotemperature proxy records are widely used to reconstruct the global climate throughout the Phanerozoic and to test macroevolutionary hypotheses. However, the spatial distribution of these records varies through time. This is problematic because heat is unevenly distributed across Earth's surface. Consequently, heterogeneous spatial sampling of proxy data has the potential to bias reconstructed temperature curves. We evaluated the spatiotemporal evolution of sampling using a compilation of Phanerozoic δ18O data. We tested the influence of variable spatial coverage on global estimates of paleotemperature by sampling a steep “modern-type” latitudinal temperature gradient and a flattened “Eocene-type” gradient, based on the spatial distribution of δ18O samples. We show that global paleotemperature is overestimated in ∼70% of Phanerozoic stages. Perceived climatic trends for some intervals might be artifactually induced by shifts in paleolatitudinal sampling, with equatorward shifts in sampling concurring with warming trends, and poleward shifts concurring with cooling trends. Yet, the magnitude of some climatic perturbations might also be underestimated. For example, the observed Ordovician cooling trend may be underestimated due to an equatorward shift in sampling. Our findings suggest that while proxy records are vital for reconstructing Earth's paleotemperature in deep time, consideration of the spatial nature of these data is crucial to improving these reconstructions.
