Research is in the midst of a period of global terraform, usually heralded under the banner of 'Open Science'. Open Science is a response from communities to an increasingly digital ecosystem, enabling new practices to emerge. Three of the major pillars of Open Science include Open Access, Open Data, and Open Source. The global paleontological community is slowly adapting to each of these as part of its culture, raising new questions around scientific practices, data standards and interoperability, and the role of paleontological research in a modern society. This chapter discusses some of the progress that the paleontological community has made in shifting towards open practices, and considers some potential avenues for the future of the field.

First high-precision U-Pb CA-ID-TIMS age for the Battle Formation (Upper Cretaceous), Red Deer River valley, Alberta, Canada: implications for ages, correlations, and dinosaur biostratigraphy of the Scollard, Frenchman, and Hell Creek formations.
Canadian Journal of Earth Sciences (advance online publication)
The Battle Formation (BFm) is a widespread Upper Cretaceous marker horizon in western Canada that records a time of low sediment-input and marks the boundary between the Edmontonian and Lancian land-vertebrate ages. Here, we present the first high-precision U-Pb CA-ID-TIMS age of 66.936 Â 0.047/0.060/0.140 Ma for the Battle bentonite, an altered vitric ash in the upper portion of the BFm at Knudsenâs Farm in the Red Deer River valley of Alberta. This age supersedes those previously reported, confirms that rates of sediment accumulation for the formation were very low (~1.40 cm/ka), and allows us to interpolate an age range of ~66.88â67.20 Ma for the BFm. Our data also provide a maximum age of ~66.88 Ma for the base of the overlying Scollard Formation, a dinosaur-rich unit. We combine our age data with calibrated magneto- and palynostratigraphic data to assess chronostratigraphic correlations among the Scollard Formation (K-ScF) of Alberta, the Frenchman Formation (FFm) of Saskatchewan, and the Hell Creek Formation (HCF) in eastern Montana. Whereas the combined data support previous interpretations that equate the age ranges of the K-ScF, FFm, and the upper one-third of the HCF in eastern Montana, they also indicate that all of the lower one-third (L3) and part of the middle one-third (M3) of the HCF in Montana are chronostratigraphically equivalent to all or part of the sub-BFm unconformity and the BFm in Alberta. Accordingly, a minimum age of ~67.20 Ma is assessed for the base of the Hell Creek Formation in its type area.

Fire in the paradise: evidence of repeated palaeo-wildfires from the Araripe Fossil LagerstÃtte (Araripe Basin, Aptian-Albian), Northeast Brazil.
Palaeobiodiversity and Palaeoenvironments (advance online publication)
Reports on Cretaceous charcoals are relatively common on a global scale and have been increasing in recent years. Fossil charcoal from the Early Cretaceous mostly belongs to conifers (and other gymnosperms) and ferns whereas angiosperms become more common only during the Late Cretaceous. However, so far, reports of Cretaceous macroscopic charcoal are rare (three) for South America. Here, charcoal is identified from the Crato, Ipubi and Romualdo formations of the Early Cretaceous Santana Group within the Araripe Basin, Brazil. The presence of charcoal provides for the first time compelling evidence for the repeated occurrence of Early Cretaceous palaeo-wildfires in this region. The charred wood remains were identified as belonging to gymnosperms, which were important components of the palaeoflora during the Cretaceous in Northeast Brazil. The results presented here provide additional evidence for the occurrence of palaeo-wildfires in Northern Gondwana during the Early Cretaceous, increasing our understanding for the relevance of such events and their influence on palaeoenvironmental dynamics.
