The asbian to arnsbergian conodonts and sequence stratigraphy of the Northumberland trough [PDF]

open access: yes, 2001
Yoredale sequences are excellent exemplars of the sequence stratigraphy model; the spacial and temporal variation of these complex shallow marine/fluvio-deltaic/ coastal plain cycles, exhibit all the uiternal facies architecture that would be expected of

Conodonts: Past, Present, Future

open access: yes, 2001
Conodonts were mostly small, elongate, eel-shaped marine animals that inhabited a variety of environments in Paleozoic and Triassic seas. Although long enigmatic, conodonts are now regarded as vertebrates and their closely controlled fossil record is not

Revision of the conodont zonation of the Wenlock–Ludlow boundary in the Prague Synform [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
The regional zonation of the Wenlock–Ludlow boundary is established for the Prague Synform using refined data from updated conodont records. The following conodont zones have been recognized in the Prague Synform: the Ozarkodina sagitta sagitta Zone, the

Devonian conodonts from Jones Island, northwest Washington

open access: yes, 1984
Two small outcrops of limestone on Jones Island, northwest Washington, have yielded Devonian conodonts. Conodonts from locality 1, on the northern shore of the island, include Icriodus cf. I. brevis Stauffer, Icriodus cf. I.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

open access: yesTectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...
