Phylogeny of Canthocamptidae (Copepoda, Harpacticoida) based on the morphology of antennae and mouthparts

Учёные записки Казанского университета: Серия Естественные науки, 2020
The plesiomorphic state of mouthparts and antennae, both characterized by dense setation and numerous spine groups, was described in a hypothetical common ancestor of all canthocamptids. This is the first time that canthocamptids have been subjected to a

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

The Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Paleopathology of a putative colossosaurian caudal vertebra (Neosauropoda: Titanosauria) from the Presidente Prudente Formation, Brazil

The Anatomical Record, EarlyView.
Abstract Studies investigating paleopathologies in sauropods remain scarce despite their relative abundance in the fossil record. In this study we report new occurrence of paleopathological features, corresponding to a neoplasm found in a middle caudal vertebra (MCT.R.2120) of an advanced titanosaur from the Presidente Prudente Formation (Bauru Basin ...

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

Biological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Calyx and epicalyx morphology in Indian Hibiscus (Malvaceae) and its taxonomic importance

Nordic Journal of Botany, EarlyView.
Hibisceae is one of the largest tribes in Malvaceae, having a diverse floral morphology. The genus Hibiscus shows a wide range of evolutionary patterns in calyx and epicalyx morphology. Genera like Abelmoschus, Azanza, Gossypium, Hibiscus,and Thespesia are separated on the basis of calyx and epicalyx morphology, meaning that the calyx and epicalyx have

Rethinking areas of endemism and barriers: perspectives for a causal historical biogeography and a critique of Schultz and Cracraft (2024)

Cladistics, EarlyView.
Abstract Historical biogeography faces a persistent conceptual and methodological dilemma concerning the nature of its central analytical units. Using the recent proposal by Schultz and Cracraft (Cladistics 40, 653) as a catalyst, this article critiques the argument that causal inference necessitates the replacement of areas of endemism with barriers ...

Morphology‐based phylogeny of longhorn beetles (Coleoptera, Cerambycidae) aligns with phylogenomics and informs higher‐level systematics

Cladistics, EarlyView.
Abstract We present a morphology‐based backbone phylogeny of Cerambycidae beetles inferred by parsimony analyses using 77 adult characters scored for 101 species. This phylogeny is largely consistent with recent phylogenomic studies regarding key placements (e.g., Parandrini stat. rev. within Prioninae, Necydalini stat. rev.

Cladistics with geometric morphometric data: The variability of the calvarium in the genus Homo

Bulletins et Mémoires de la Société d’Anthropologie de Paris
Over the last 30 years, several protocols to adapt 3D geometric morphometric data to cladistics have been developed. Strongly criticised, these protocols are only occasionally used in palaeoanthropology, despite the obvious heuristic potential of such an

Comparative endocranial anatomy in the crocodylians Leidyosuchus canadensis and Stangerochampsa mccabei from the upper Cretaceous of Alberta, Canada

Journal of Anatomy, EarlyView.
Leidyosuchus canadensis and Stangerochampsa mccabei share endocranial features such as posterior projection of a neurovascular canal in the maxilla and a paratympanic sinus system most similar to those of small‐bodied and young extant crocodylians, suggesting that these pedomorphic features may reflect the ancestral crocodylian condition.
