Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?
The Anatomical Record, EarlyView.Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...

Scientia Marina, 2012 Aphanius dispar (Rüppell, 1829) is a common marine-euryhaline teleost fish in the Near East that has undergone considerable intraspecific differentiation. Otolith morphology is used to analyse the diversity within A.

The Anatomical Record, EarlyView.Abstract Saber‐tooths, extinct apex predators with long and blade‐like upper canines, have appeared iteratively at least five times in the evolutionary history of vertebrates. Although saber‐tooths exhibit a relatively diverse range of morphologies, it is widely accepted that all killed their prey using the same predatory behavior. In this study, we CT‐

Morphotectonics of the Tasso Stream - Sagittario River valley (Central Apennines, Italy)
Journal of Maps, 2019 This work presents the morphotectonic map of the Tasso Stream-Sagittario River valley, located in the Central Abruzzo area (Marsica region), in one of the areas of highest average elevation in the Apennines chain between two main intermontane basins (i.e.

On the Pleistocene Flora of Canada [PDF]
Geological Society of America Bulletin, 1890 I. GEOLOGY OF THE DEPOSITS. BY SIR WM. DAWSON. General Geology of the Pleistocene The Pleistocene deposits of Canada may be defined as consisting of three principal members, which may be characterized as follows, in ascending order: 1. The Till, or lower bowlder clay, a tough or sometimes sandy clay, containing local and traveled stones and bowlders,

Terrestrial Effects Of Nearby Supernovae In The Early Pleistocene [PDF]
The Astrophysical Journal Letters, Volume 826, Number 1, 2016, 2016 Recent results have strongly confirmed that multiple supernovae happened at distances ~100 pc consisting of two main events: one at 1.7 to 3.2 million years ago, and the other at 6.5 to 8.7 million years ago. These events are said to be responsible for excavating the Local Bubble in the interstellar medium and depositing 60Fe on Earth and the Moon ...

Morphological diversity of saber‐tooth upper canines and its functional implications
The Anatomical Record, EarlyView.Abstract Elongated upper canine teeth, commonly known as saber‐teeth, have evolved three times within the sub‐order Feliformia. The species that wielded them flourished throughout the Cenozoic and have historically been separated into two morphological groups: the dirk‐tooths with longer, flatter canines, and the scimitar‐tooths with shorter, serrated ...
