The Middle Cenomanian basal series of Planinica, Western Serbia [PDF]
Geološki Anali Balkanskoga Poluostrva, 2002 Sedimentary rocks of the Upper Cretaceous basal series found at the village of Planinica, Western Serbia, are composed of thick coarse clastics and beds and intercalations of medium- to fine-grained clastics. The series lies transgressively over Jurassic

Quarterly Journal of the Geological Society of London, 1903 Two ammonites belonging to the family Hildoceratidæ have been found by members of the Cotteswold Naturalists' Field-Club, and have been given to me to name. Both happen to be new forms; and they are of particular interest—one for the geological information which it gives, the other from a biological point of view.

A New Approach to the Accretive Growth of Surfaces Via Hyperbolical Kinematics
Mathematical Methods in the Applied Sciences, Volume 48, Issue 16, Page 15349-15363, 15 November 2025.ABSTRACT In the current work, we introduce the accretive growth of surfaces by using hyperbolical geometry. First, we describe hyperbolical kinematics along a generating curve to construct accretive surfaces having a hyperbolical cross‐section. The obtained surfaces are not only the ones having hyperbolical cross‐sections but also their material points

The Depositional Record, Volume 11, Issue 4, Page 1084-1106, September 2025.The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.
