The rise of predation in Jurassic lampreys [PDF]

open access: yesNature Communications, 2023
Lampreys, one of two living lineages of jawless vertebrates, are always intriguing for their feeding behavior via the toothed suctorial disc and life cycle comprising the ammocoete, metamorphic, and adult stages. However, they left a meager fossil record,

A new neornithischian dinosaur from the Upper Jurassic Tiaojishan Formation of northern China [PDF]

open access: yesPeerJ
The Middle and Late Jurassic Yanliao Biota is different from other contemporaneous fossil assemblages in that it lacks neornithischian dinosaurs. Here, we report a new, early-diverging neornithischian, Pulaosaurus qinglong gen. et sp.

Jurassic scorpionflies (Mecoptera) with swollen first metatarsal segments suggesting sexual dimorphism [PDF]

open access: yesBMC Ecology and Evolution, 2021
Background Sexual dimorphism is widespread in insects. The certain specialized structures may be used as weapons in male–male combats or as ornaments to enhance mating opportunities.

A bony-crested Jurassic dinosaur with evidence of iridescent plumage highlights complexity in early paravian evolution [PDF]

open access: yesNature Communications, 2018
A number of paravian dinosaurs have been described from the Jurassic Yanliao biota, but these have tended to be morphologically similar to Archaeopteryx. Here, Hu. describe the new paravian dinosaur, Caihong juji gen. et sp. nov., which possesses a suite

Investigating the Morphogenesis and Replacement of Lamprey Toothlets Using Synchrotron Imaging. [PDF]

open access: yesJ Morphol
Toothlet replacement is a conserved feature in lampreys. We describe the mechanism at tissue level and quantify the determining factors, thus providing the basis for studies into a deep homology of cyclostome toothlets and gnathostome teeth. ABSTRACT Teeth are a key innovation that underpinned the adaptive radiation of jawed vertebrates; however, their

Earliest filter-feeding pterosaur from the Jurassic of China and ecological evolution of Pterodactyloidea [PDF]

open access: yesRoyal Society Open Science, 2017
Pterosaurs were a unique clade of flying reptiles that were contemporaries of dinosaurs in Mesozoic ecosystems. The Pterodactyloidea as the most species-diverse group of pterosaurs dominated the sky during Cretaceous time, but earlier phases of their ...
