Carbonate Sedimentation Rates Today and in the Past: Holocene of Florida Bay, Bahamas, and Bermuda vs. Upper Jurassic and Lower Cretaceous of the Jura Mountains (Switzerland and France)

open access: yesGeologia Croatica, 2003
Lagoonal to intertidal sediments from the Holocene in Florida Bay,on the Bahamas, and in Bermuda are compared to similar facies in theKimmeridgian and Berriasian of the Swiss and French Jura Mountains.Dating by 14C permits the estimation of sediment ...

Geochemical and Seismic Constraints on the Role of Mud Diapirs in Petroleum Migration and Accumulation in the Recôncavo Basin, NE Brazil

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 433-447, April 2026.
ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

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 ...

Upper Jurassic–Lower Cretaceous Incertae Sedis Organisms from Mirdita Zone, Albania

open access: yesAlbanian Journal of Natural and Technical Sciences
Incertae sedis, also referred to as microproblematica, are organisms with an uncertain systematic position. In micropaleontological studies—particularly those focused on paleoenvironmental research or bathymetric zoning of marine environments—these ...

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.
