Abstract We investigate the fractal characteristics of diverse natural objects and discuss their possible applications. Fractal dimensions suture lines ammonite shells, granite textures, portions river network in Onega Ladoga lakes basin multi-fractal spectra varved clay sedimentation these were calculated. It is shown that shells can be used to identify ammonites. textures granites applied imp...

We report on remains of the buccal apparatus and possible associated structures for Late Cretaceous ammonite Maorites seymourianus from López de Bertodano Formation (Antarctic Peninsula). This is first description these family Kossmaticeratidae. Further, we discuss most likely taphonomic processes taking place that allowed this exceptional preservation. Reflectance Transformation Imaging (RTI) ...

A Hildoglochiceras -rich horizon is reported from a thin carbonate intercalation within the siliciclastic Upper Jurassic Jhuran Formation of Jara Dome, western Kachchh Mainland. The specimens have been used for first population-level study genus based on multivariate analysis. High phenotype instability in large sample confirms occurrence transient forms between morphospecies. Key morphological...

Unknown fossil collections from the Bakony Mts, collected by J. Nosky Jnr. during his mapping activity in 1940s and 1950s were found storage facility of Hungarian Geological Institute 2010s. In these materials Upper Bajocian (Middle Jurassic) Som-hegy Bakonybél (formerly known as part Pénzeskút) some specimens determined 1959 ‘Canaliphylloceras’ nov. gen. sp.’ However, never published faunal st...

The end-Triassic mass extinction overlapped with the eruption of the Central Atlantic Magmatic Province (CAMP), and release of CO2 and other volcanic volatiles has been implicated in the extinction. However, the timing of marine biotic recovery versus CAMP eruptions remains uncertain. Here we use Hg concentrations and isotopes as indicators of CAMP volcanism in continental shelf sediments, the ...
