Hello All,

next Tuesday we will have the ‘New’s flash’ by Mikko Haaramo. He will walk us through four interesting and fairly fresh publications from the field of paleosciences! Everyone is warmly welcome!

We have also started to compile info and stuff for the excursion in plans:

https://www.dropbox.com/sh/b72skyafhf2w5oy/AAAL2tj4lZ3jrpgaEVOCsp2Ha?dl=0 Now is you change to influence the locations we should visit! (I’m not sure if you can upload or edit things in this folder if you are not a member of that dropbox group, if you are interested to be a part of the planning team please inform me and I will invite you. You can also send suggestions and opinions to me by email!)

See you on Tuesday 25.10.2016 at 16.00 in C108, Physicum!

Hi All,

Next Tuesday Indre Žliobaitė is going to talk about “Ecometrics beyond limits”, here is a short abstract:

“Ecometrics is a methodology for analysis of environments via common traits of species. It is presumed that surviving in different environments requires different functional traits, such as types of teeth. By characterizing what kind of trait distributions species assemblages have one can model environments and reconstruct environmental conditions from the past. I will talk about the computational side of ecometrics and new developments in ecometric analysis with case studies in East Africa.”

Everyone is warmly welcome to join!

Hi All,

Next week we will have practice presentations for SVP meeting. If you want to try out and get comments for your own presentation let me know, there is still room (also others than SVP talks are welcome, but it should take max 12min).

See you on Tuesday 4.10.2016 at 16.00 in C108, Physicum!

Hi All,

next week we will have a visitor from University of Cambridge; Rachel O´Meara will give us a talk titled “Understanding enamel formation and growth in non-mammalian cynodonts”. I hope I can see many of you in this interesting club meeting!

Abstract: “The evolution of mammals from non-mammals is associated with the linked evolutionary origin of several important characters, including diphyodont tooth replacement, mammal-like rapid juvenile growth and determinate adult growth. These characters likely evolved in the extinct cynodont and basal mammaliamorph lineages of the Triassic and early Jurassic, with Morganucodon the most basal known mammaliamorph to have had both mammal-like growth and diphyodonty. Histological techniques to assess periodic enamel increments have not previously been applied to non-mammalian cynodonts and mammaliamorphs, and are likely to improve understanding of their dental replacement and growth patterns. We prepared histological thin sections of postcanines of eight species of non-mammalian cynodont, and teeth from crown mammals and diapsids. Polarised light microscopy revealed two orders of incremental lines, resembling the daily laminations and longer period striae of Retzius of crown mammalian enamel, in all non-mammalian cynodont specimens. We used MANOVA to compare two measures of enamel growth, daily secretion rate (DSR) and crown extension rate (CER), in extant groups and in two non-mammalian cynodont groups, non-probainognathians and mammaliamorphs. DSR in all cynodont species was similar to that of non-hypsodont mammals. However, CER was extremely high in non-probainognathians, with enamel extending rapidly in sheath-like layers, in comparison with the gradual accretion of enamel in the more crownward mammaliamorphs. This is consistent with the reduction in rates of dental replacement in mammaliamorphs, which would permit slower crown extension, while greater rates of replacement in more basal non-probainognathians may have required more rapid rates of formation. In addition, it is possible that the low rate of ameloblast differentiation, which causes low CER in mammaliamorphs, may be coupled with reduced function of osteoblasts. This would suggest reduced rates of bone growth during late molar formation in these animals, which would be consistent with a more mammal-like, abrupt termination of growth in mammaliamorphs in comparison with more basal cynodonts, which likely had a more extended period of adult growth.”

Hi All,

next week we will have a (discussion) session which introduces classes and courses suitable for paleo studies. The target is our new students, but veterans of our subject are very welcome to join and share their own experiments, and maybe you learn something new at the same time!

See you on Tuesday 13.9.2016 at 16.00 in C108, Physicum!

Pps. I have now updated the picture of Björn Kurtén on our webpage, thanks Mikael for the photo! https://blogs.helsinki.fi/bk-club/who-was-bjorn-kurten/

Hi All,

let’s start the autumn term of Kurten club on next week by a planning meeting! If anyone has ideas what we can do this autumn, please don’t hesitate to bring them up. I already have some names in my list to give talks, but all possibilities are considered. If you can’t come physically, you can always send suggestions by email.

See you on Tue 6.9.2016 at 16.00 in C108, Physicum!
