Welcome to Sepkoski's Online Genus Database!
strata.geology.wisc.edu/jack/

"The purpose of this database is to allow users to easily search and summarize Sepkoski's global genus compendium on the basis of Evolutionary Fauna, Phylum, or Class. You can recover customized lists of genera and their stratigraphic ranges (according to Sepkoski) as well as summaries of genus richness and taxonomic rates of evolution. As time permits, I will be adding additional features to this database, including the ability to search for a genus name and to obtain lists of taxa by stratigraphic interval."

🚨R package StratPal update🚨
Full integration with the FossilSim package to study effects of #taphonomy and #ecology on #phylogenetic trees with sampled ancestors, and simplified handling of categorical niche models 😁

mindthegap-erc.github.ioStratigraphic Paleobiology Modeling PipelinesThe fossil record is a joint expression of ecological, taphonomic, evolutionary, and stratigraphic processes (Holland and Patzkowsky, 2012, ISBN:978-0226649382). This package allowing to simulate biological processes in the time domain (e.g., trait evolution, fossil abundance), and examine how their expression in the rock record (stratigraphic domain) is influenced based on age-depth models, ecological niche models, and taphonomic effects. Functions simulating common processes used in modeling trait evolution or event type data such as first/last occurrences are provided and can be used standalone or as part of a pipeline. The package comes with example data sets and tutorials in several vignettes, which can be used as a template to set up one's own simulation.

Join us in #Utrecht 🇳🇱 for a meeting on #reproducibility in #stratigraphy, #Earth 🌍 and #climate history and #astrochronology. We offer workshops on #StratigraphicModelling, #Age-DepthModels and #CodeReproducibility for #earthscience professionals and students. If you want to join a field trip to the #Devonian and #Carboniferous of #Belgium 🇧🇪, make sure to register quickly!

Chronozone (Geology terminology ⛰️)

A chronozone or chron is a unit in chronostratigraphy, defined by events such as geomagnetic reversals, or based on the presence of specific fossils. According to the International Commission on Stratigraphy, the term "chronozone" refers to the rocks formed during a particular time period, while "chron" refers to that time period. ...

Strike-slip fault (Geology terminology ⛰️)

In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, suc...

maps - Example maps of New Zealand mainland (>73,000 localities), Raukumara Peninsula (>13,000 localities), and detail of Mahia Peninsula (212 localities), to illustrate the density and distribution of fossil localities recorded in the Fossil Record File.
screen shot - Several different query facilities are provided by the FRED interface into the FRF, the most comprehensive of which is the ‘Advanced Query’. The figure depicts a partially populated Advanced Query search screen. Search fields are grouped into various categories (locality, stratigraphy, taxonomic, etc.) and a selection of operators (equals, contains, numeric inequalities, etc.) to allow a series of Boolean statements to be constructed. Full instructions are provided in the on-line user manual.

photos - Left – Two of the most common fossil taxa recorded in the Fossil Record File, a rimu pollen grain, Dacrydium cupressinum (top; scale bar = 20 μm) and the foraminifer Globoquadrina dehiscens (bottom; scale bar = 200 μm). Right (stereo pair) – One of the rarest taxa recorded, the mosasaur Rikisaurus tehoensis (V19/f0068; scale bar = 200 mm). The microfossils have each been recorded more than 5000 times; the mosasaur only once.
