Description of the research base
About the project
The main goal of this research is a revision of fossil turtles
(Testudinata) from Czechia and Poland. Much historical fossil turtle
material from these countries has not been revised in decades and,
surprisingly, some specimens even in a century. Progress in the
understanding of fossil turtle phylogeny and taxonomy that occurred
over the last decades renders many original identifications dubious
or invalid. Even worse, many specimens were published in local, non-
English language publications and never figured, which virtually
excluded them from the current scientific discourse. Besides
historical specimens, new material has been discovered recently and
awaits scientific evaluation. Therefore, the actual total diversity
of turtles in Central Europe (meaning Czechia and Poland) and its
changes since the Mesozoic remain unknown. Fossil turtles are good
indicators of paleoclimatic reconstructions, that provide novel data
that allows reconstructing zonation of the environment, the mean
annual temperature, and – together with the remaining herpetological
fauna – precipitation, as well. However, for proper paleoclimatic
reconstructions, proper taxonomic identification is a prerequisite.
The fossil record from Czechia contains Mesozoic and Cenozoic
representatives of turtles. For example, Miocene turtles are
abundant and high diversity is expected. Similar conditions are
preserved in the Polish fossil record, where especially Triassic and
Cenozoic deposits are rich. As for now, Czech and Polish
biodiversity is more or less similar. Analogous conditions can be
expected in the past and a simultaneous study of the Czech and
Polish material will allow avoiding taxonomic misidentification and
diagnosing specimens in a broader context. Besides traditional
methods, the proposed project will use modern imaging technologies
like photogrammetry or 3D surface scanners to obtain the most
complete and accurate digital models, which will be shared with the
international scientific community.

Apart from materials stored at the capitol, we travelled to visit a
regional museum. At first, we started in
Teplice, where dozens of fossil turtles mostly
from Břeštany fossil site are deposited. The collection of
trionychids is large and other researchers are welcome to examine
local treasures.
05-10.04.2024
Both participants of the project spent three days at the
National Museum in Prague, where hundreds of
specimens are stored. An unbelievable amount of specimens showed so
many details that they even reveal the sexual dimorphism and
ontogenetic development. A fantastic further step in the project!
03.04.2024
The fellow Milan Chroust and his mentor Tomasz Szczygielski spent
whole day at the collections of the
Chlupáč's Museum of Earth History at the
Charles University in Prague. Several specimens were digitized and
will be accessible in the prepared database.
03.04.2024
Tomasz Szczygielski visited the
Charles University in Prague. Besides the
study the specimens housed in the collection, he held a lecture
about the world of ancient turtles. He introduced the oldest fossil
turtles and summarized the current knowledge about the Mesozoic and
Cenozoic taxa not only from Poland and Czechia. The students and
professors were excited at how rich the Czech and Polish fossil
record is.
25.03.2024
Milan Chroust held a science talk for the public audience at
the National Museum in Prague. The talk focused on the evolution of
turtles and included fossils from Poland and Czechia. The concept of
the Polonez Bis project No. 2022/45/P/NZ8/00600 was introduced as
well. The heated discussion with the audience showed the general
interest in the topic and therefore further talks are requested.
21.03.2024
The
Institute
of Paleobiology, PAS prepared a workshop for students from the
ZDOLNI program by
Krajowy
Fundusz na rzecz Dzieci. The fellow Milan Chroust and his
mentor Tomasz Szczygielski did not focus solely on the research on
fossil turtles. The students later identified fossils by themselves
and tried several different methods to interpret the data.
11.03.2024
Milan Chroust presented preliminary results of the current project
to at the scientific staff of the Institute of Paleobiology, PAS.
Further discussion improved the current interpretation of selected
data and additional tips were included in the project.
28.11.2023
Milan Chroust held a science talk about his Polonez Bis project No.
2022/45/P/NZ8/00600 at the
University
of Warsaw. He discussed with the academic members and students
the occurrences of fossil turtles in Czechia and Poland.
21.11.2023
Turtle workshop for scholarship holders of the ZDOLNI Program run by
the
Krajowy
Fundusz na rzecz Dzieci was held at the Institute of
Paleobiology of the Polish Academy of Sciences.
The kids learned the differences between the bones and dermal scutes
and they built their own turtle.
10.11.2023
Fellow and his mentor studied a very important specimen of
Glarichelys
knorri housed in the
Regional Museum in Jasło. This is yet another
piece of the puzzle!
09.11.2023
After some time, the researchers visited
ISEZ PAN again to study the collection of
extant and fossil turtles. Together with Dr. Georgalis, the curator
of the herpetological collection, they digitized several important
species.
6.07-7.07.2023
The fellow and his mentor studied hundreds of fossils housed at
the
Museum
of the Earth in Warsaw. Together, they found very important
holotypes which were considered to be lost. Another puzzle in the
research of fossil turtles was solved!
22.06.2023
Another collection was visited. The fellow and his mentor visited
Prof. Piotr Węgierek at the University of Silesia in Katowice. A
very important fossil of a Neogene marine turtle was documented and
transported for further analysis.
21.06.2023
The researchers visited a collection of the Institute of the
Institute of Systematics and Evolution of
Animals, PAS to study fossil turtles. Together with Dr.
Georgalis, the curator of the herpetological collection, they
discovered several amazing fossils important for their further
research.
19.06-20.06.2023
The fellow Milan Chroust and his mentor Tomasz Szczygielski attended
a
Kick-off meeting in Kraków organised by the NCN.
They both attended a workshop on career development, conducted by
the POLONEZ BIS programme’s partner – CRAC-Vitae – and learned more
about publishing in Open Access.
16.06.2023
The fellow Milan Chroust and his mentor Tomasz Szczygielski together
with other members of the
Institute of Paleobiology, PAS prepared a
workshop for students from the program ZDOLNI by
Krajowy Fundusz na rzecz Dzieci. The workshop
was focused on the research of fossil turtles and students
identified fossils by themselves and tried several different methods
to interpret the data.
