Phylodynamic models can be used to estimate diversification trajectories from time-calibrated phylogenies. Here we apply two such phylogenies of non-avian dinosaurs, a clade whose evolutionary history has been widely debated. Although some authors have suggested that the experienced decline in diversity, potentially starting millions years before end-Cretaceous mass extinction, others group remained highly diverse right up until Cretaceous-Paleogene (K-Pg) boundary. Our results show model assumptions, likely with respect incomplete sampling, large impact on whether dinosaurs appear long-term or not. The are also sensitive topology and branch lengths phylogeny used. Developing comprehensive sampling bias, building larger more accurate phylogenies, necessary steps for us determine dinosaur diversity was not extinction.

Untangling the patterns and drivers behind diversification extinction of highly diversified lineages remains a challenge in evolutionary biology. While insect has been widely studied through "Big Four" orders (Coleoptera, Hymenoptera, Lepidoptera Diptera), fifth most diverse order, Hemiptera, often overlooked. Hemiptera exhibit rich fossil record are present-day ecosystems, with many closely associated to their host plants, making them crucial group for studying how past ecological shifts-such as mass extinctions floral turnovers-have influenced diversification. This study leverages birth-death models Bayesian framework estimate diversity dynamics. Our results reveal that global changes flora over time significantly shaped trajectories Hemiptera. Two major faunal turnovers particularly diversification: (i) aftermath Permo-Triassic (ii) Angiosperm Terrestrial Revolution. analyses suggest clades was driven by floristic shifts combined competitive pressures from overlapping niches. Leveraging extensive allowed us refine our understanding across hemipteran lineages.

Over the past decade, a new set of methods for estimating dated trees has emerged. Originally referred to as fossilized birth–death (FBD) process, this single model expanded family models that allows researchers coestimate evolutionary parameters (e.g., diversification, sampling) and patterns alongside divergence times variety applications from paleobiology real-time epidemiology. We provide an overview models. explore ways in which these correspond quantitative paleobiology, FBD process provides framework through neontological paleontological approaches phylogenetics macroevolution can be unified. also challenges associated with applying models, particularly eye toward fossil record. conclude review by discussing several exciting avenues inclusion data phylogenetic analyses.

With ~14,000 extant species, ants are ubiquitous and of tremendous ecological importance. They have undergone remarkable diversification throughout their evolutionary history. However, the drivers diversity dynamics not well quantified or understood. Previous phylogenetic analyses suggested patterns associated with Angiosperm Terrestrial Revolution (ATR), but these studies overlooked valuable information from fossil record. To address this gap, we conducted a comprehensive analysis using large dataset that includes both ant record (~24,000 individual occurrences) neontological data (~14,000 occurrences), tested four hypotheses proposed for diversification: co-diversification, competitive extinction, hyper-specialization, buffered extinction. Taking into account biases in record, found three distinct periods (the latest Cretaceous, Eocene, Oligo-Miocene) one extinction period (Late Cretaceous). The hypothesis between stem crown is supported. Instead, support hyper-specialization hypotheses. environmental changes ATR, mediated by angiosperm radiation, likely played critical role buffering against favoring providing new niches, such as forest litter arboreal nesting sites, additional resources. We also hypothesize decline during Late Cretaceous was due to hyper-specialized morphology, which limited ability expand dietary niche changing environments. This study highlights importance holistic approach when studying interplay past environments trajectories organisms.

Resolving the evolutionary relationships of early diverging ('basal') ornithischian dinosaurs is a challenging topic in palaeontology, with multiple competing hypotheses on phylogenetic heterodontosaurids, 'hypsilophodontids', and other early-diverging forms. These cannot be directly compared because they are derived from differently constructed datasets (i.e. distinct samples taxa characters). This study aims to address these issues by revising combining into single analysis order create most comprehensive dataset for investigation ornithischians. A diphyletic model Dinosauria supported, silesaurs nesting as members Ornithischia. Heterodontosauridae resolved clade non-genasaurian ornithischians, rejecting potential relationship Marginocephalia. 'Hypsilophodontid' span neornithischian ornithopod stem, Thescelosauridae sister taxon Cerapoda. more restricted Ornithopoda composed five main clades: Hypsilophodontidae, Rhabdodontomorpha, Elasmaria, Dryosauridae Ankylopollexia. Hypsilophodontidae valid clade, reduced two European Barremian taxa. Rhabdodontomorpha does not contain Muttaburrasaurus originally proposed, but instead expands include North American formed Convolosaurus, Iani Tenontosaurus. Elasmaria contains all non-dryomorph Gondwanan ornithopods, its possessing body plans.

Abstract Gondwanan dinosaur faunae during the 20 Myr preceding Cretaceous–Palaeogene (K/Pg) extinction included several lineages that were absent or poorly represented in Laurasian landmasses. Among these, South American fossil record contains diverse abelisaurids, arguably most successful groups of carnivorous dinosaurs from Gondwana Cretaceous, reaching their highest diversity towards end this period. Here we describe Koleken inakayali gen. et sp. n., a new abelisaurid La Colonia Formation (Maastrichtian, Upper Cretaceous) Patagonia. is known skull bones, an almost complete dorsal series, sacrum, caudal vertebrae, pelvic girdle and hind limbs.

Leveraging our phylogeny estimates, explore rates morphological evolution across ceratosaurian lineages, finding them to be particularly high for elaphrosaurine noasaurids around base Abelisauridae, before Early radiation latter clade.

Ornithischians form a large clade of globally distributed Mesozoic dinosaurs, and represent one their three major radiations. Throughout evolutionary history, exceeding 134 million years, ornithischians evolved considerable morphological disparity, expressed especially through the cranial osteodermal features most distinguishable representatives. The nearly two-century-long research history on has resulted in recognition numerous diverse lineages, many which have been named. Following formative publications establishing theoretical foundation phylogenetic nomenclature throughout 1980s 1990s, proposed names ornithischian clades were provided with definitions. Some these definitions proven useful not changed, beyond way they formulated, since introduction. names, however, multiple definitions, making application ambiguous. Recent implementation International Code Phylogenetic Nomenclature ( ICPN , or PhyloCode ) offers opportunity to explore utility previously established taxon names. Since Articles are be applied retroactively, all published prior its remain informal (and ineffective) light Code. Here, we revise dinosaur clades; revisit 76 preexisting review recent historical use, formally establish Additionally, introduce five new names: two for robustly supported later-diverging hadrosaurids ceratopsians, uniting heterodontosaurids genasaurs, nodosaurids. Our study marks key step towards formal dinosaurs.
