    Published 2024-08-01
    “…The detrital zircon provenance analysis indicates zircon grains originated mostly in the Jurassic, with limited contributions from the Cretaceous, Permian, and Paleocene. The new age for LMF allows correlating these beds to the upper section of the continental Río Leona Formation in the southern Austral-Magallanes Basin. …”

    RESULTS OF THE TECTONOPHYSICAL STUDY IN THE DZHANKHOT THRUST ZONE (NORTHWESTERN CAUCASUS) by A. V. Marinin, T. Yu. Tveritinova

    Published 2022-09-01
    “…The relevance of the research topic is found on the reason that despite the obvious importance of these overthrust nappes in the structure of the Greater Caucasus there is still lack of in-situ observational data on the detailed structure of thrust zones and on tectonic stress distribution pattern therein.As a result of the structural and geological studies of small disjunctive and plicative forms in the Upper Cretaceous and Paleocene sediment contact along the Dzhankhot thrust, there were identified the major structural and tectonic deformation patterns and the areal distribution of tectonic deformations depending on the distance to the thrust. …”

    Homeotic evolution in the mammalia: diversification of therian axial seriation and the morphogenetic basis of human origins. by Aaron G Filler

    Published 2007-10-01
    “…<h4>Conclusion/significance</h4>Clusters of homeotic transformations mark the emergence point of mammals in the Triassic and the radiation of therians in the Cretaceous. A cluster of homeotic changes in the Miocene hominoid Morotopithecus that are still seen in humans supports establishment of a new "hominiform" clade and suggests a homeotic origin for the human upright body plan.…”

    Giant paleo-seafloor craters and mass wasting associated with magma-induced uplift of the upper crust by K. O. Omosanya, K. Duffaut, T. M. Alves, O. E. Eruteya, S. E. Johansen, N. Waldmann

    Published 2022-03-01
    “…Estimates of 1-dimensional uplift based on well data show that uplift occurred due to the intrusion of magma in Upper Cretaceous to Lower Eocene strata. Our findings also prove that subsurface fluid plumbing associated with the magmatic sills was prolonged in time and led to the development of several vertical fluid flow conduits, some of which triggered mass wasting in Neogene to Recent times. …”

    Synthetic analysis of trophic diversity and evolution in Enantiornithes with new insights from Bohaiornithidae by Case Vincent Miller, Jen A Bright, Xiaoli Wang, Xiaoting Zheng, Michael Pittman

    Published 2024-04-01
    “…However, more quantitative data from across the enantiornithine tree is needed to refine this prediction. By the Early Cretaceous, enantiornithine birds had diversified into a variety of ecological niches like crown birds after the K-Pg extinction, adding to the evidence that traits unique to crown birds cannot completely explain their ecological success.…”
