there are still 6 days left to apply to join my group at Senckenberg Museum Frankfurt as a PhD Student in #Paleobiology! Are you interested in how the rock record shapes our undersanding of macroevolutionary dynamics of #plants in the #Mesozoic?

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. ...

Do you want to know how the structure of the rock record affects your reconstructions of #biodiversity, #evolution rates or trait evolution? The groundwork for doing this has been laid down in the field of #StratigraphicPaleobiology but until now no software tools have been available to researchers in #paleobiology and #geoscience to evaluate distortion of their #FossilRecord.

Join the webinar on Building modeling pipelines for stratigraphic paleobiology in #RSoftware by my PhD student @Niklas_Hohmann in the Paleoverse lecture series hhttps://palaeoverse.org/lectures this Thursday at 4 PM UTC to learn how to use the new package StratPal developed in my European Research Council (ERC) project #MindTheGap

You can find the package with extensive documentation here: https://mindthegap-erc.github.io/StratPal/
More on the project: https://mindthegap-erc.github.io/

If you are interested in working with us on #StratigraphicPaleobiology, structure of the fossil record, and development of #OpenSource research software, please get in touch!

Corroborating written history with ancient DNA: The case of the Well-man described in an Old Norse saga

"Here we apply palaeogenomic analysis to human remains excavated from a medieval well at the ruins of Sverresborg Castle in central Norway. In Sverris Saga, the Old Norse saga of King Sverre Sigurdsson, one passage details a 1197-CE raid on the castle and mentions a dead man thrown into the well. Radiocarbon dating supports that these are that individual’s remains."

Many people think the history of the Earth is hard to decipher. The geological record jumbles everything up. We set out to fact-check this in my ERC Starting Grant MindTheGap. Focusing on the mode of evolution, because that is something that we can only glean from long records, longer than anything accessible to observation or experimentation today.

Thanks to collaboration with Peter Burgess we used forward models to simulate formation of carbonate rocks and see how completeness and stratigraphic resolution affect the reconstructions. Guess what! The geological record is With a bit of understanding of #sedimentology and #physics we can test is with computer experiments and it turns out even very patchy rock strata will let us reconstruct the correct mode of evolution. This opens a lot of possibilities, especially for the #microfossil community: your data is priceless to understand #microevolution.

Also a big shoutout to an excellent review process at PCI Paleo, the thoughtful editors and reviewers, and to the lead author Niklas Hohmann for #code #reproducibility effort that meets the most stringent standards. Check out our software at https://lnkd.in/eJkwhhuh

Anatomy and size of Megateuthis, the largest belemnite

"We collected data of the proportions of the hard parts of some Jurassic belemnites in order to learn about shared characteristics in their gross anatomy. This knowledge is then applied to the Bajocian genus Megateuthis, which is the largest known belemnite genus worldwide."
