The Brazilian Academy of Sciences is a non-profit organization (ABC 2019) that has completed one century of existence in 2016. A series of special publications was organized by the Annals of the Brazilian Academy of Sciences (AABC) in celebration of this important date (e.g., Kellner 2017, Crespilho 2018, Cavaleiro 2018). Here we have the pleasure to introduce the final of these volumes gathering 20 original contributions in paleontology, the science dedicated to the study of all evidences of life that have been preserved in layers of deep time. The topics presented here vary from the description of new species and specimens of flying reptiles, dinosaurs, and crocodylomorphs to studies on biogeography, osteohistology, and specific contributions provided by microfossils. Over 70 authors from different countries were involved in this volume, showing the increasing international integration of Brazilian paleontologists.Overall, the study of fossils has gotten more and more diversified, which has also been represented by the papers recently published in the AABC. This includes new discoveries of rare specimens that expand the distribution of certain groups (e.g., Richter et al. 2017), studies on how Brazilian material might provide answers to more general questions such as the extinction of dinosaurs (e.g., Brusatte et al. 2017), discovery of distinct pattern of dental replacement in lizards (e.g., Chavarría-Arellano et al. 2018), and efforts to better understand complicated questions like the interpretation of cranial structures (e.g., Cheng et al. 2017) and new feeding modes (Kellner and Calvo 2017) of flying reptiles.But that is not all. Brazilian researchers have also been concerned with ethical questions regarding on how specimens are collected (Mansur et al. 2017), a problem that has been addressed by several scientists around the world (e.g., Lipps and Granier 2009, MacFadyen 2011).Paleontologists working in Brazil have also applied distinct techniques in the study of fossils. Paleohistology, through thin-section analysis, has a great potential for providing new information of the life history of extinct vertebrates, as accessing growth rates, ontogenetic stages, estimated age, and dental replacing patterns (e.g., Sayão 2003, Melo et al. 2019. This is an area that could be developed further, addressing more complex questions (e.g.,

Continuing with the evaluation of the impact of different scientific fields for the bibliometric indexes of the Annals of the Brazilian Academy of Sciences (AABC) that was recently started (Kellner 2020a, b), here I focus on the publications regarding Mathematical, Chemical, Earth and Engineering Sciences during 2018 considered in the 2019 Journal Citation Reports (JCR). Concerning Mathematical Sciences, only six papers were published, two of which were cited during 2019-one and two times, respectively. This results in an Article Citation Factor (ACF, see Kellner 2020a) of 0.3333, showing that only about one third of the articles published by the AABC in this area were cited in the following year. The Impact Factor (IF) of Mathematical Sciences of these papers in 2019 is 0.500-much lower than the 2019 IF of this journal (1.280). If only the two cited papers are considered, the Reescalated Article Impact Factor (RAIF, see Kellner 2020a) is 1.500. In Engineering Sciences, a total of seven manuscripts were published, three of which were cited once during 2019, resulting in an ACF of 0.4286, which is slightly higher than the ACF of Agrarian and Biological Sciences (Kellner 2020b). RAIF is 1.000 and if only this scientific field is considered, the IF of the AABC would be 0.429. A different situation is found in Earth Sciences. The total number of articles published during 2018 is 28, but two were not retrieved by JCR, resulting in a Missing Article Index (MAI, see Kellner 2020b) of 0.0714. From the 26 articles considered by JCR 2019, 16 were cited, producing an ACF of 0.6154. Most articles received one or two citations, but one was cited 17 times (Marengo et al. 2018), contrasting with all others. If all papers are considered, RAIF is 2.875, but if the most cited article is excluded, the value drops to 1.933. The same happens with the IF if only publications of this scientific field are considered, changing from 1.160 to 1.769 if the contribution of Marengo et al. (2018) is included. The last area that is analyzed here is Chemical Sciences that has also provided the greatest contribution to the 2019 IF of the AABC considering the papers published in 2018 (Kellner in prep). A total of 41 articles were published, including two special volumes (Cavaleiro 2018, Crespilho 2018). From the 41 published papers, 29 were cited resulting in an ACF of 0.7073. RAIF is 3.621 and IF is 2.561-almost the double of the 2019 IF of this journal (1.280). Examining the evolution of these specific areas in the AABC compared to the overall rates of submissions, rejection, and publication (Fig. 1), Mathematical (Fig. 1a) and Engineering Sciences (Fig. 1b) have similar trajectories, with a small but steady growth. However, the numbers are clearly much lower than in other scientific fields that have contributed to the AABC. How to cite KELLNER AWA. 2020.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
