Reassessment of the iconic Oligo‐Miocene heterodont dolphin Squalodon: a redescription of the type species S. grateloupii

open access: yesPapers in Palaeontology, Volume 11, Issue 2, March/April 2025.
Abstract Since its description in 1840, the toothed whale Squalodon was conceptualized as a transitional form between archaeocetes‐like Basilosaurus and the modern toothed whales (Odontoceti). The cranial morphology of Squalodon approximates that of modern odontocetes; however, their dental patterning more closely resembles that of archaeocetes ...

Colonization of the Americas, 'Little Ice Age' climate, and bomb-produced carbon: their role in defining the Anthropocene [PDF]

open access: yes, 2015
A recently published analysis by Lewis and Maslin (Lewis SL and Maslin MA (2015) Defining the Anthropocene. Nature 519: 171–180) has identified two new potential horizons for the Holocene−Anthropocene boundary: 1610 (associated with European colonization

Timing Is Everything

open access: yesPaleoceanography and Paleoclimatology, Volume 39, Issue 12, December 2024.
Abstract Deep ocean sediments document past environmental changes over space and time. The information gleaned from such deposits allows scientists to test climate models that are used to predict future climate change. However, the causes and consequences of changing climate can be unraveled only if geological data from different regions are ...

Chronostratigraphy and geochronology: a proposed realignment [PDF]

open access: yes, 2013
We propose a realignment of the terms geochronology and chronostratigraphy that brings them broadly into line with current use, while simultaneously resolving the debate over whether the Geological Time Scale should have a “single” or “dual” hierarchy of

Micropalaeontological dating of the Prémontré mammal fauna (MP10, Prémontré Sands, EECO, early late Ypresian, Paris Basin) [PDF]

open access: yes, 2016
At their type locality the Prémontré Sands contain fairly well-diversified organic-walled microfossil assemblages attributable to the lower part of dinoflagellate cyst Zone D9 and indicating a transition from an estuarine to a lagoonal depositional ...

Conodonts from a potential Eifelian/Givetian Boundary Stratotype at jbel Ou Driss, southern Ma’der, Morocco [PDF]

open access: yes, 1989
Conodonts from a section at Jbel Ou Driss in the Ma'der (pre-Sahara of Morocco) with neritic and pelagic megafaunas, are studied in an attempt to define the Eifelian/Givetian boundary. The conodont succession ranges from the T. kockelianus Zone into the
