Classified within the oofamily Krokolithidae, thei histo- and ultrastructures are conservative throughout geological time, characterised by inverted-trapezoid-shaped shell units that grow from highly spaced basal knobs and present a diagnostic tabular ultrastructure. Here, we report 327 eggshell fragments from a new fossil site from the Maastrichtian of the Southern Pyrenees, Veracruz 1, and erect a new oogenus and oospecies, Pachykrokolithus excavatum oogen. et oosp. nov. characterised by crocodyloid morphotype and a prominent rugosocavate ornamentation. Eggshells from the slightly older locality of Blasi 2b, previously reported as aff. Krokolithidae, are also assigned to this new ootaxon. Different crocodylomorph taxa coexisted during the Late Cretaceous of the Tremp Basin, hindering the attribution of Pachykrokolithus excavatum oogen. et oosp. nov. to a single clade. Nevertheless, allodaposuchid eusuchians were dominant in this ecosystem, and are the most probable producers of Pachykrokolithus excavatum oogen. et oosp. nov. eggs. info:eu-repo/grantAgreement/ES/MICINN/FJCI-2020-044561-I info:eu-repo/grantAgreement/ES/MICINN/PID2021-122612OB-I00 info:eu-repo/grantAgreement/ES/MICINN/PLEC2021-008203/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.4 2023 PALEONTOLOGY 31 / 57 = 0.544 2023 Q3 T2 0.578 2023 Agricultural and Biological Sciences (miscellaneous) 2023 Q1 3.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Pérez Pueyo, Manuel Universidad de Zaragoza (orcid)0000-0002-6792-1563 Puértolas Pascual, Eduardo Universidad de Zaragoza (orcid)0000-0003-0759-7105 Núñez Lahuerta, Carmen Mateus, Octavio Bauluz, Blanca Universidad de Zaragoza (orcid)0000-0002-4970-6333 Bádenas, Beatriz Universidad de Zaragoza (orcid)0000-0003-1112-524X Canudo, José Ignacio Universidad de Zaragoza (orcid)0000-0003-1732-9155 2000 655 Universidad de Zaragoza Dpto.
