Conference on planetary geology
Tomáš Kohout of the Institute of Geology CAS, who has been also long working for University of Helsinki, delivered a speech at the conference Cosmic Projects taking place within the Czech Space Week in Villa Lanna, Prague, on November 12, 2021. His contribution was related to mapping of the asteroid Didymos. The conference programme and individual presentations are published here; specifically, the talk of T. Kohout can be viewed by clicking here (starting from 42 min. of the recording).
Institute of Geology staff scoring in Photogenic Science competition
The Institute staff submitted a total of 24 photos for the present competition rund, of which 11 passed to the semifinals. This may be the reason why was the Institute granted the Special Award for the most attractive photographic performance. Moreover, several photographs were ranked high in two categories: 1st and 3rd position in the category of Muse in Science; 1st and 3rd position in the category Scientists and Household Chores. The awarded employees were Lenka and Pavel Lisý and Michal Filippi. The photos and information about the competition are available on the Photogenic Science website.
Czech–Chinese research of fossil tropical vegetational “Pompeii”, Inner Mongolia, China
Respected scientific international journal Review of Palaeobotany and Palynology dedicated a special issue (Vol. 294) to important results of the international team of Czech and Chinese palaeobotanists and palynologists at the Wuda locality, Inner Mongolia, China. The international team collaborated on six excavations (2011–2018) of a tropical forest 298 Myr old. Two members of the Laboratory of Palaeobiology and Palaeocology, Jiří Bek and Jana Votočková-Frojdová are co-authors of nine papers from this special volume describing important finds of fossil lycophytes, sphenophytes and ferns as they have been buried by volcanic ash after a huge volcanic eruption like in the legendary Roman city of Pompeii.
Scientists of the Institute contributing to Czech Acad Sci press
The last issue of the science-promotion magazine A/Science and Research, published by the Czech Academy of Sciences, presented interesting articles on mushrooms – a highly topical subject in autumn time. The texts were significantly contributed by our colleague Jan Borovička. The same issue also contains a brief comment by Michal Filippi on the article dealing with “invisible gold”, which raised interest among journalists worldwide recently.
A new style of sandstone disintegration documented
A recent paper in Geomorphology was also contributed by Michal Filippi of the Institute of Geology. It presents a newly recognized weathering style of sandstone outcrops. Its essence lies in a disconnection of smaller parts of rock along lithological and other discontinuities, which allows the material to dilate and damage the protective bio-crust on the cliff face. This results in a more effective function of erosion factors in the disconnected parts and their accelerated disintegration.
The Deanʾs Award
Hedvika Weinerová was awarded the Deanʾs Award for best students in the Doctoral programme for the year 2021. Her study at the Faculty of Science of Masaryk University is focused on changes in the composition of carbonate sediments of the Barrandian area with respect to Devonian bioevents and sea-level changes.

An award for a GLI scientist
Anna Žigová was awarded the Bronze medal of the Czech Academy of Agricultural Sciences on 4 March 2021. This medal was awarded for an exceptional contribution to the development of science and research in the field of agriculture. For additional information click here. Congratulations!
Progress in the study of cadmium
Cadmium (Cd) is a toxic metal widely occurring in the environment, often due to the human activity. The employees of the Institute of Geology of the Czech Acad Sci have developed a method for measuring Cd isotopes in biological samples using thermal ionization mass spectroscopy (TIMS). The results published in the prestigious analytical journal Talanta represent a useful tool in the quality control of chemical analyses for all laboratories involved in the analysis of cadmium in biogenic materials.

The oldest trilobites had babies with large heads and long spines
Trilobites are the most iconic inhabitants of the Paleozoic seas. These arthropods possess an exoskeleton that was hardened by calcium carbonate shortly after they hatched from the egg. Owing to this fact, their developmental stages are often preserved in the fossil record. In their new paper, Lukáš Laibl with his colleagues from Freie Universität Berlin described the development of trilobite Fritzolenellus lapworthi from Cambrian strata of Newfoundland, from tiny individuals smaller than one millimeter up to the nearly 20 cm long adults. Juveniles of Fritzolenellus show a large cephalon and distinct spines on their body. Based on a detailed comparison of Fritzolenellus babies with those of other Cambrian trilobites, the authors showed that features seen in Fritzolenellus have the original morphology inherited from the last common ancestor and can be thus used as a reference group when studying the ontogeny of other trilobites.

Promotion of geosciences: a new open-air rock exhibition
On the occasion of the International Day of Museums and Galleries, a new outdoor geological exposition "Selected Rocks of the Rakovník District" will be opened on Tuesday, May 18, 2021 from 4 pm near the Museum T.G.M. in Rakovník. A number of subjects participated in the preparation of the exhibition, including the Institute of Geology represented by Karel Žák and Jiří Adamovič. This exhibition is one of many examples of the outreach of scientists-geologists beyond the area of "hard science" in conveying their knowledge to the general public. Those interested can visit the exhibition free of charge during the museum's opening hours.
