Observations of tear‐drinking by lepidopterans on moose (Alces americanus americanus) in northeastern North America

open access: yesEcosphere, Volume 16, Issue 11, November 2025.
Abstract Lepidoptera have long been known to feed on the tears of vertebrates as a presumed source of minerals or nutrients. While this unusual behavior has been observed in a variety of species, only a single previous record has been documented outside of the tropics. Here, we present the first documentation of moths visiting the eyes of a bull moose (

Ammonite-benthic Foraminifera turnovers across the Lower-Middle Jurassic transition in the Lusitanian Basin (Portugal) [PDF]

open access: yes, 2013
This paper describes and characterises the co-occurrence of ammonite and benthic foraminiferal assemblages across the São Gião outcrop (Central Portugal), a reference section for the Lower-Middle Jurassic boundary in the Lusitanian Basin.

A New Approach to the Accretive Growth of Surfaces Via Hyperbolical Kinematics

open access: yesMathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 15349-15363, 15 November 2025.
ABSTRACT In the current work, we introduce the accretive growth of surfaces by using hyperbolical geometry. First, we describe hyperbolical kinematics along a generating curve to construct accretive surfaces having a hyperbolical cross‐section. The obtained surfaces are not only the ones having hyperbolical cross‐sections but also their material points

Lower and Middle Cenomanian ammonites from the Morondava Basin, Madagascar [PDF]

open access: yes, 2013
Lower and Middle Cenomanian ammonite assemblages have been collected on a bed-by-bed basis from localities at Vohipaly and Mahaboboka, Madagascar, as well as from outcrops around Berekata, all in the Morondava Basin, southwest Madagascar.

Systematic utility of the phytosaur post‐dentary mandibular region

open access: yesPapers in Palaeontology, Volume 11, Issue 6, November/December 2025.
Abstract Phytosaurs, crocodile‐like archosaurs from the Late Triassic, are known for their unique skull shape, whereas their mandibles are poorly studied. Two‐dimensional (2D) geometric morphometric (GM) analysis is commonly used on dinosaurs and mammals.

Remagnetization of Lower Cretaceous Limestones in the Western Tethyan Himalaya and Its Tectonic Implications for the India‐Asia Collision

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract The drift history of the Tethyan Himalaya provides key constraints on the India‐Asia collision, Himalayan‐Tibetan orogenesis, and associated global climate change. Here we present rock magnetic, petrographic, geochronologic, and paleomagnetic results of the Bolinxiala Formation limestones in the western Tethyan Himalaya.

LATE BARREMIAN-EARLY APTIAN AMMONITES FROM THE MAIOLICA FORMATION NEAR CESANA BRIANZA (LOMBARDY BASIN, NORTHERN ITALY)

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2017
The ammonite faunas collected in three marly interbeds of the Maiolica limestone exposed near Cesana Brianza (Como province, Lombardy) are described in this paper. The age of the first and second interbeds is Late Barremian.

Sexual dimorphism in the Bathonian morphoceratid ammonite Polysphinctites tenuiplicatus [PDF]

open access: yesActa Palaeontologica Polonica, 2016
Asphinctites tenuiplicatus [M] and Polysphinctites secundus [m] from the Asphinctites tenuiplicatus Zone (Early Bathonian), are usually considered as a sexual dimorphic pair, although authors describe them as separate species.
