“…As an example, Cretaceous eolian sandstones, representing the development of an arid climate, are widely distributed in the mid‐latitude areas of Asia (Hasegawa et al, ; Hasegawa, Tada, Ichinnorov, & Minjin, ; Jiang & Li, ; Jiang & Pan, ; Jiang, Pan, & Fu, ). Recently, Amiot et al (, ) proposed that the early Cretaceous climate was warm temperate and dry, with mean air temperatures of 15 ± 6°C at 35°N as evidenced by using the isotopic oxygen signatures from continental vertebrates in China.…”

“…The Sichuan Basin was situated at a paleolatitude between 20°N and 30°N during the Cretaceous, which was near the basin's current position (Singsoupho, Bhongsuwan, & Elming, ), and was surrounded by mountain ranges (Amiot et al, ; Meng, Wang, & Hu, ; Philippe, Boura, Oh, & Pons, ; Wang, Fan, Zhang, & Zhang, ). The highlands of the South China Block located east and south of the basin and the Longmenshan and Qinling‐Dabie Mountains, extending from the west to the north, already existed in the western and northern basin during the Cretaceous (Figure ).…”

Pedogenic features of paleosols preserved in the lower and upper Cretaceous sedimentary strata of the western Sichuan Basin, China, were described and examined in terms of their macromorphology and micromorphology, mineralogy, and geochemistry. These Cretaceous paleosols (entisols, inceptisols, and aridisols) are analogous to modern soil orders based on soil taxonomy (Soil Survey Staff, 2014). A quantitative reconstruction of paleoclimates inferred from the geochemical composition of paleosol horizons, depth to carbonate nodules, and the stable oxygen isotopic composition of pedogenic carbonates in paleosols indicates that a cool-arid climate associated with short-term subhumid fluctuations prevailed in the early Cretaceous (Hauterivian) and a cool-arid climate regime existed in the late Cretaceous (Maastrichtian) of the Sichuan Basin. Atmospheric CO 2 concentrations estimated from the paleosol barometer indicated values between 156 ± 138 and 753 ± 339 ppmv for the Hauterivian and between 110 ± 71 and 235 ± 77 ppmv for the middle-lateMaastrichtian. An overall coupling between atmospheric pCO 2 and paleotemperature occurred in the Sichuan Basin, while the covariations are likely linked to global cooling events in the Maastrichtian and/or are likely associated with the Faraoni oceanic anoxic event (F-OAE) during the late Hauterivian. Paleoclimate variations in the Sichuan Basin were controlled by regional paleogeography, the prevalence of subtropical high-pressure systems, monsoonal circulation, and the atmospheric CO 2 level in the early and late Cretaceous.

“…Although this study does not consider palaeocoastline and climatic barriers as these are poorly known in contrast to the well‐constrained continental positions (Upchurch, ), effects of changing coastlines across entire networks are accounted for by incorporating SL into the models. Climatic barriers almost certainly would have limited dispersal of certain dinosaurian taxa, both within and between continental landmasses, and evidence for climatic control on terrestrial tetrapod diversity has been detected in Permo‐Triassic Pangaean (Sidor et al ., ; Ezcurra, ; Whiteside et al ., , ) and Cretaceous Gondwanan (Benson et al ., ; Amiot et al ., ) communities. However, climatic barriers were most likely far less pronounced than in the present day as through much of the Mesozoic pole‐equator gradients were as low as at any other point in the entire Phanerozoic (Huber et al ., ; Holtz et al ., ; Mannion et al ., , ) and dinosaurs appear to have been able to migrate large distances and transcend climate belts in order to colonize new environments (Longrich, ).…”

Aim To reconstruct dinosaur macro‐biogeographical patterns through the Mesozoic Era using a network‐based approach. We test how continental fragmentation affected dinosaur macro‐biogeographical structure and evolutionary rates. Location A global occurrence database of dinosaur families from the Late Triassic to the end‐Cretaceous was used for this study. Methods Biogeographical and geographical network models were constructed. Continental landmasses were linked by direct continental contact and sea level (SL)‐conditioned connections in geographical networks, and by shared dinosaur families in biogeographical networks. Biogeographical networks were run with raw, novel and first‐step connections for all dinosaur, ornithischian, theropod, and sauropodomorph taxa. Results Geographical connectedness declines through time, from peak aggregation in the Triassic–Jurassic to complete separation in the latest Cretaceous. Biogeographical connectedness shows no common trend in the raw and novel connection network models, but decreases through time while showing some correlation with continental fragmentation in most of the first‐step network models. Despite continental isolation and high SLs, intercontinental faunal exchange continued right up to the end of the Cretaceous. Continental fragmentation and dinosaurian macro‐biogeographical structure do not share a common pattern with dinosaurian evolutionary rates, although there is evidence that increased continental isolation resulted in increased origination rates in some dinosaurian lineages. Spatiotemporal sampling biases and early Mesozoic establishment of family‐level distribution patterns are important drivers of apparent dinosaur macro‐biogeographical structure. Main conclusions There is some evidence to suggest that dinosaur macro‐biogeographical structure was influenced by continental fragmentation, although intercontinental exchange of dinosaur faunas appears to have continued up to the end of the Cretaceous. Macro‐biogeographical patterns are obscured by uneven geographical sampling through time and a residual earlier Mesozoic distribution which is sustained up to the end of the Cretaceous.

“…dinosaurs) were experiencing a phase of decline. Regional evidence exists for smaller-scale faunal turnovers, such as that between neosuchian crocodylomorphs and choristoderes in the earliest Cretaceous, which might relate to climatic preferences and/or ecologically selective extinctions (Matsumoto & Evans, 2010;Amiot et al, 2015;Matsumoto, Manabe & Evans, 2015).…”

Biotic and environmental dynamics through theLateJurassic–EarlyCretaceous transition: evidence for protracted faunal and ecological turnover

et al. 2016

The Late Jurassic to Early Cretaceous interval represents a time of environmental upheaval and cataclysmic events, combined with disruptions to terrestrial and marine ecosystems. Historically, the Jurassic/Cretaceous (J/K) boundary was classified as one of eight mass extinctions. However, more recent research has largely overturned this view, revealing a much more complex pattern of biotic and abiotic dynamics than has previously been appreciated. Here, we present a synthesis of our current knowledge of Late Jurassic-Early Cretaceous events, focusing particularly on events closest to the J/K boundary. We find evidence for a combination of short-term catastrophic events, large-scale tectonic processes and environmental perturbations, and major clade interactions that led to a seemingly dramatic faunal and ecological turnover in both the marine and terrestrial realms. This is coupled with a great reduction in global biodiversity which might in part be explained by poor sampling. Very few groups appear to have been entirely resilient to this J/K boundary 'event', which hints at a 'cascade model' of ecosystem changes driving faunal dynamics. Within terrestrial ecosystems, larger, more-specialised organisms, such as saurischian dinosaurs, appear to have suffered the most. Medium-sized tetanuran theropods declined, and were replaced by larger-bodied groups, and basal eusauropods were replaced by neosauropod faunas. The ascent of paravian theropods is emphasised by escalated competition with contemporary pterosaur groups, culminating in the explosive radiation of birds, although the timing of this is obfuscated by biases in sampling. Smaller, more ecologically diverse terrestrial non-archosaurs, such as lissamphibians and mammaliaforms, were comparatively resilient to extinctions, instead documenting the origination of many extant groups around the J/K boundary. In the marine realm, extinctions were focused on low-latitude, shallow marine shelf-dwelling faunas, corresponding to a significant eustatic sea-level fall in the latest Jurassic. More mobile and ecologically plastic marine groups, such as ichthyosaurs, survived the boundary relatively unscathed. High rates of extinction and turnover in other macropredaceous marine groups, including plesiosaurs, are accompanied by the origin of most major lineages of extant sharks. Groups which occupied both marine and terrestrial ecosystems, including crocodylomorphs, document a selective extinction in shallow marine forms, whereas turtles appear to have diversified. These patterns suggest that different extinction selectivity and ecological processes were operating between marine and terrestrial ecosystems, which were ultimately important in determining the fates of many key groups, as well as the origins of many major extant lineages. We identify a series of potential abiotic candidates for driving these patterns, including multiple bolide impacts, several episodes of flood basalt eruptions, dramatic climate change, and major disruptions to oceanic systems. The J/K t...
