“…Using equation ( 2) and the δ 18 O aw values calculated from turtles and crocodilians, those temperatures range from 12 to 22°C (mean value: 17 ± 10°C, 2 s.d., n = 2), which would be expected of a freshwater tropical environment and further indicates that those fish were also autochthonous. The measured δ 18 O p values in Tiupampa fauna are high and comparable to those measured in the terrestrial ecosystems of the Songliao basin (mean δ 18 O = 22.20 ± 1.65 ‰, 2 s.d., n = 57; Huang et al, 2013;Gao et al, 2015;Zhang et al, 2018) and Nanxiong basin (mean δ 18 O = 24.53± 1.92 ‰, 2 s.d., n = 6; Yin et al, 2023, but not as high as those measured in desertic environments (Lécuyer et al, 1999;Schoeninger et al, 2000), therefore being more in line with a dry environment. The δ 18 O aw values are also in accordance with climatic conditions measured nowadays in Pakistan or South China, with a mean annual temperature around 20°C and a mean precipitation of a few hundred millimeters per year (IAEA, 2022).…”

PremiseThe ecological conditions that constrain plants to an environmental niche are assumed to be constant through time. While the fossil record has been used previously to test for niche conservatism of woody flowering plants, additional studies are needed in other plant groups especially since they can provide insight with paleoclimatic reconstructions, high biodiversity in modern terrestrial ecosystems, and significant contributions to agriculture.MethodsWe tested climatic niche conservatism across time by characterizing the climatic niches of living herbaceous ginger plants (Zingiberaceae) and woody dawn redwood (Metasequoia) against paleoniches reconstructed based on fossil distribution data and paleoclimatic models.ResultsDespite few fossil Zingiberaceae occurrences in the latitudinal tropics, unlike living Zingiberaceae, extinct Zingiberaceae likely experienced paratropical conditions in the higher latitudes, especially in the Cretaceous and Paleogene. The living and fossil distributions of Metasequoia largely remain in the upper latitudes of the northern hemisphere. The Zingiberaceae shifted from an initial subtropical climatic paleoniche in the Cretaceous, toward a temperate regime in the late Cenozoic; Metasequoia occupied a more consistent climatic niche over the same time intervals.ConclusionsBecause of the inconsistent climatic niches of Zingiberaceae over geologic time, we are less confident of using them for taxonomic‐based paleoclimatic reconstruction methods like nearest living relative, which assume a consistent climatic niche between extant and extinct relatives; we argue that the consistent climatic niche of Metasequoia is more appropriate for these reconstructions. Niche conservatism cannot be assumed between extant and extinct plants and should be tested further in groups used for paleoclimatic reconstructions.
