The Pliocene environment of Antarctica [PDF]

Papers and Proceedings of the Royal Society of Tasmania, 1996
Debate continues about the environment of Antarctica during intervals in the Pliocene (5.2-1.8 Ma), particularly during the Late Pliocene (3.5-1.8 Ma). Two schools of thought - dynamic versus stable ice sheet - have developed. One hypothesis calls for the Antarctic ice sheet to vary dramatically, for Antarctica at times to be vegetated and for circum-

The complex interaction between mammalian herbivores, climate, soil and fire has shaped the evolution and distribution of plant spinescence across biogeographical realms

New Phytologist, EarlyView.
Evolution of spinescence in mimosoid legumes. Summary The evolutionary arms race between plants and herbivores led to numerous plant adaptations, including spinescence. However, the balance between herbivory and abiotic conditions in the evolution of spinescence remains unclear. We integrated phylogenetic, geographic, and trait data for 2686 species of

Cenozoic tropical carbonate platforms in the Santos Basin, SE Brazilian Margin

Sedimentology, EarlyView.
ABSTRACT Tropical carbonate platforms accompanied the latitudinal shifts of the tropical belt throughout the Cenozoic. Their flat‐topped geometries were influenced by a specific set of processes, including climate and sea‐level changes, carbonate facies, tectonics and continental runoff.

Evidence for the continental origin of Pliocene deposits in the central Baja California peninsula, Mexico, and implications for controls on biodiversity

Sedimentology, EarlyView.
ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

A new genus of hemibelideine possum (Marsupialia: Pseudocheiridae) from New Guinea and Australia, including a Lazarus taxon from the Vogelkop Peninsula

Records of the Australian Museum
A new genus of gliding marsupial (Hemibelideinae; Pseudocheiridae) is proposed for several possums previously known only as fossils: ‘Petauroides’ ayamaruensis Aplin, 1999 (Quaternary of the Vogelkop Peninsula of western New Guinea), Pseudocheirus ...

Colonisation History of Freshwater Snails Across the Atlantic and Mediterranean Islands: Insights From Mercuria (Littorinimorpha, Hydrobiidae)

Zoologica Scripta, EarlyView.
ABSTRACT Islands harbour unique biodiversity, and depending on their geological origin, they have fundamentally different colonisation histories: continental islands may contain relict faunas shaped by vicariance and sporadic gene flow, whereas oceanic islands must have been colonised across open seas, often through long‐distance dispersal events ...

Through the Sands of Time: Evolutionary History and Systematics of the Awl‐Headed Snakes (Colubridae: Lytorhynchus) in the Saharo‐Sindian Region

Zoologica Scripta, EarlyView.
ABSTRACT The psammophilous colubrid genus Lytorhynchus is widely distributed in the deserts of the Saharo‐Sindian region and adjacent areas. The taxonomy of the genus and the number of recognised species have remained unstable since the last taxonomic revision in 1970, with differing views on the taxonomic status of L. gaddi and L. kennedyi.

The relationship between form and function of the carnivore mandible

The Anatomical Record, Volume 309, Issue 9, Page 2487-2506, September 2026.
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 ...

Beach Gold and Heavy Mineral Concentrates on Tiwai Spit Gravel Strand Plain, Southland, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.
The Holocene Tiwai Spit on Foveaux Strait is a 12 km by 2 km gravel‐dominated strand plain, ∼10 m above present sea level. Gravel clasts are dominated by well‐rounded quartz cobbles, pebbles and granules derived from Otago Schist 200 km to the north in evolving river drainage systems during late Cenozoic.
