First occurrences of Trionychidae (Testudines, Cryptodira) from the Miocene of Poland: Detailed cranial anatomy and biogeographic implications

open access: yesJournal of Anatomy, Volume 249, Issue 2, Page 314-337, August 2026.
Fossil finds from three Middle Miocene sites in Poland reveal the northernmost known presence of trionychid turtles in Europe, tentatively identified as Trionyx cf. vindobonensis, suggesting a warmer climate that supported thermophilic species in Central Europe during this period. Abstract Modern trionychids (Testudines, Cryptodira) have a pan‐tropical

Climate conditions on the South‐Iberian Palaeomargin during the latest Pliensbachian to early Toarcian: A mineralogical and geochemical study from hemipelagic deposits

open access: yesSedimentology, Volume 73, Issue 5, Page 1631-1663, August 2026.
ABSTRACT The integrated analysis of lithofacies, mineralogy and geochemistry of the hemipelagic marine succession exposed in La Cerradura section (South‐Iberian Palaeomargin) provides new information to characterise the palaeoenvironmental conditions during the latest Pliensbachian to early Toarcian, including the Jenkyns Event.

Bivalve mollusk assemblages on São Paulo's northern continental shelf, southeast Brazil

open access: yesBrazilian Journal of Biology
Soft bottom bivalve mollusc assemblages were sampled along a depth gradient (10 to 100 m) on the northern São Paulo shelf during the austral summer and winter. A one-way analysis of similarity permutation test revealed there was no seasonal difference in

Bivalve Mollusk Paleoecology: Trophic and Environmental Reconstruction from Stable Isotopes, Sclerochronology and Shell Damage [PDF]

open access: yes, 2006
I examined how predatory damage in bivalve shells can be used to assess the trophic importance of species, how oxygen isotope ratios in shells can be used to estimate past salinity, and how Colorado River flow affects growth rates in a bivalve mollusk. I
