Oldest Cretaceous latimeriid elucidates cranial evolution in derived and extant coelacanths (Actinistia, Latimeriidae)

open access: yesPapers in Palaeontology, Volume 12, Issue 2, March/April 2026.
Abstract The fossil record of coelacanths (Actinistia) is diminished by several nominal gaps that obscure vital information pertaining to the clade's evolutionary history. Latimeriidae, the family that includes the extant coelacanth Latimeria, in addition to the Cenozoic, has an outstanding missing gap of 50 myr during the Mesozoic, with no records of ...

Sedimentary evolution of the Torrecilla Reef Complex in response to tectonically forced regression (Early Kimmeridgian, Northern Spain)

open access: yes, 2006
The early Kimmeridgian Torrecilla Reef Complex in the northern Iberian Basin of Spain consists of a fringing reef composed of eight accretionary units. The first four were deposited along a steep margin.

Kimmeridgian hardground-sequence boundary from the Mesozoic margin of the Holy Cross Mountains (central Poland): implications for the evolution of the northern Tethyan carbonate shelf

open access: yesFacies, 2017
The sedimentary succession in central Poland records significant changes in facies at the turn of the Planula and Platynota zones in the Upper Jurassic, expressed by the drowning of the ramp-type platform and development of an extensive isochronous marl ...

The Jurassic of Denmark and Greenland: The Upper Jurassic of Europe: its subdivision and correlation [PDF]

open access: yesGeological Survey of Denmark and Greenland Bulletin, 2003
In the last 40 years, the stratigraphy of the Upper Jurassic of Europe has received much attention and considerable revision; much of the impetus behind this endeavour has stemmed from the work of the International Subcommission on Jurassic Stratigraphy.

Tectonostratigraphic Evolution of the Guyana Basin: Implications for Sediment Routing and Slope Stability

open access: yesBasin Research, Volume 38, Issue 2, March–April 2026.
Seismic profile across the Guyana Basin showing the main tectonostratigraphic units and an order‐of‐magnitude increase in sedimentation rates since the Middle Miocene corresponding with the onset of sedimentation dominated by mass transport deposits. ABSTRACT The Guyana Basin developed in an evolving tectonic setting, but a lack of subsurface data has ...

The early origin of Iguanodontia: new insights into the macroevolution, diversity and biogeography of the clade

open access: yesPalaeontology, Volume 69, Issue 2, 2026.
Abstract Iguanodontia (Dinosauria, Ornithischia) is a speciose group of herbivorous dinosaurs that include the famous genus Iguanodon, one of foundational members of the clade Dinosauria. Despite their very long history of research, several aspects of their systematic relationships and their evolutionary history remain somewhat nebulous.
