Gridded fossil CO2 emissions and related O2 combustion consistent with national inventories 1959-2018
<p>GCP-GridFED (version 2019.1) is a gridded fossil emissions dataset that is consistent with the national CO<sub>2</sub> emissions reported by the Global Carbon Project (GCP). GCP-GridFEDv2019.1 provides monthly fossil CO<sub>2 </sub>emissions for the period 1959-2018 at a spatial resolution of 0.1° × 0.1°. The gridded emissions estimates are provided separately for fossil CO<sub>2</sub> emitted by the oxidation of oil, coal and natural gas, with mixed international bunker fuels considered separately, as well as for the calcination of limestone during cement production. GCP-GridFED also includes gridded uncertainties in CO<sub>2 </sub>emission, incorporating differences in uncertainty across emissions sectors and countries, and gridded estimates of corresponding O<sub>2</sub> uptake based on oxidative ratios for oil, coal and natural gas.</p> <p>GCP-GridFED was produced by scaling monthly gridded emissions for the year 2010, from the Emissions Database for Global Atmospheric Research (EDGAR; version 4.3.2; Janssens-Maenhout et al., 2019), to the national annual emissions estimates compiled as part of the 2019 global carbon budget (GCB-NAE) for the years 1959-2018 (Friedlingstein et al., 2019).</p> <p>The data description article is under review.</p>

Data from: New cranial fossils of the Jurassic turtle Neusticemys neuquina and phylogenetic relationships of the only thalassochelydian known from the Eastern Pacific
Neusticemys neuquina is a turtle from the Upper Jurassic of the Neuquén Basin, Patagonia, Argentina. Here we describe in detail a new skull, lower jaw, and a vertebra, utilizing both traditional anatomical description and computed tomography (CT). New diagnostic cranial characters of Ne. neuquina are: a round depression on the ventral surface of the basisphenoid, a relatively larger oval foramen nervi trigemini and reduced and steepened triturating surfaces on both the maxilla and dentary. The new morphological information presented in this study was included in a phylogenetic analysis, the primary result of which was recovery of Ne. neuquina within Thalassochelydia. Characters recognized as synapomorphies of this clade include (1) anterolateral recess of the anterior surface of the quadrate positioned lateral to the processus trochlearis oticum, (2) presence of a fossa on the supraoccipital-opisthotic-exoccipital contact area, (3) foramina anterius caroticus cerebralis located close together but independently perforating the basisphenoid, and (4) presence of the splenial in the mandible. Two contrasting dispersal scenarios may explain how this species of Thalassochelydia can be found outside of Europe. The presence of Ne. neuquina in the Neuquén Basin could be the consequence of an early dispersion event, for which we lack intermediate forms, or it may be the result of a later event once the clade was already established in Europe.
Data of fossils and sections of the Geobiodiversity Database (GBDB)
<p>Geobiodiversity database (GBDB, www.geobiodiversity.com) is a comprehensive stratigraphic and palaeontological database and was started in 2006. It is geological section-based and include data of over 26 500 geological sections and over 114 000 fossil taxa.</p> <p>The stratigraphic data in the GBDB are based on those published in Chinese literature since 1920s. By November 2020, all stratigraphic horizons and nearly all published geological sections can be searched and browsed in the GBDB. The GBDB fossil occurrence data are included in the stratigraphic records and can be queried and outputted. The palaeontological data are linked to the fossil collections from individual geological sections and borehole cores. The data include taxonomy (species, genus, family, order, class and division), major group, synonym (opinion data with different authors) and description (key features). Most fossil collections and occurrences of all sections from China are included in the GBDB. Subsequent authors in further study amended a portion of fossil taxa from these sections. In this way, there are also plenty of opinion data in the GBDB.</p> <p>The GBDB was designed to facilitate regional and global scientific collaborations focusing on palaeobiodiversity, systematics, palaeogeography, palaeoecology, regional correlation, and quantitative stratigraphy.</p> <p> </p>
