Two new Miocene limpets (Fissurellidae) from southern California, with notes on other fossil occurrences of the family in northwestern North America [PDF]

open access: yes, 2019
Two new fissurellid limpets (Mollusca: Gastropoda: Fissurellidae), Fissurella? stantoni n. sp. and Scelidotoma aldersoni n. sp., are described from Miocene deposits in southern California. Fissurella? stantoni is described from a single specimen from the

A new genus and species of sabretooth, Oriensmilus liupanensis (Barbourofelinae, Nimravidae, Carnivora), from the middle Miocene of China suggests barbourofelines are nimravids, not felids [PDF]

open access: yes, 2020
Since the early 2000s, a revival of a felid relationship for barbourofeline sabretooths has become popular due to recent discoveries of fragmentary fossils from Africa.

Evaluating the African arid corridor hypothesis: A meta‐analysis including the phylogenetic and biogeographical history of Sesamothamnus

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise We examined the African arid corridor (AAC) disjunction pattern of vascular plants between northeastern and southwestern Africa in the context of geological and climatic events since the late Miocene. We developed a phylogenetic and biogeographical framework for the arid‐adapted genus Sesamothamnus (Pedaliaceae), a classic example of ...

The relationship between form and function of the carnivore mandible

open access: yesThe Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Depositional characteristics and evolution of Miocene deep-water channel systems in block A of Lower Congo-Congo Fan Basin, West Africa

open access: yesShiyou shiyan dizhi, 2021
Researches on the depositional characteristics, evolution and constraining factors of deep-water channel systems are the key factors to reveal the "source-sink" process at continental margin and make big breakthroughs in deep-water hydrocarbon ...

Early Pliocene Varanus (Squamata, Varanidae) remains from Megalo Emvolon, Thessaloniki, Greece

open access: yesThe Anatomical Record, EarlyView.
The article describes new cranial and postcranial varanid material from Megalo Emvolon Lower Pliocene vertebrate fossil site near Thessaloniki. The fossils, likely representing a single individual, are referred to Varanus cf. marathonensis. Abstract This study describes new fossil varanid material from a recently discovered fossil spot (MVL site) at ...

Magnetic fabric of the late Miocene extrusive rocks of the Combia Volcanic Province: Tectonic implications for the northern Andes

open access: yesEarth and Planetary Physics
The accretion of the Panama–Chocó Block to the South American Plate partially drove the geological setting of the northern Andes. This event occurred in different collisional stages that are recorded in Oligocene–middle Miocene deformed rocks of the ...

REEFS AND BIOACCUMULATIONS IN THE MIOCENE DEPOSITS OF THE NORTH CROATIAN BASIN – AMAZING DIVERSITY YET TO BE DESCRIBED

open access: yesRudarsko-geološko-naftni Zbornik, 2016
During the early stages of the Middle Miocene transgression marine biota invaded the newly formed Paratethys Sea. Reefs and reef-like structures particularly flourished with life, supported by the favourable climate conditions.
