Scientific topics

The topics of the congress will include all aspects of palaeontology. Tentative themes of scientific sessions include the following:

Theme 1

Early life, Cambrian explosion, and later macroevolutionary events

Convener: Yukio Isozaki (University of Tokyo), Renbin Zhan (Nanjing Institute of Geology and Palaeontology)


Theme 2

Secular fluctuations in microbialite development throughout Earth’s history

Convener: Yoichi Ezaki (Osaka Metropolitan University), Jianbo Liu (Peking University)

Microbialites are organo-sedimentary rocks with a long geologic record on Earth. Microbial activity is ubiquitous today and in the past, and has played a key role in the creation of Earth environments throughout geologic time. Through studies of microbialites, we can understand the long-term rise and fall of microorganisms, the nature of their environments, and their interrelationships. This session is relevant to microbial palaeontology, palaeoecology, palaeoenvironment, organo-mineralisation, sedimentology, mass extinction events, and other related topics. Reports on experimental approaches using living microorganisms are also welcome.


Theme 3

Mesozoic and Paleozoic Oceanic Anoxic Events

Convener: Reishi Takashima (Tohoku University)

Oceanic Anoxic Events (OAEs) record pronounced change in the paleoceanography and marine ecosystems associated with global perturbation of carbon cycle. This session focuses on stratigraphic, paleoenvironmental and paleontological studies of the Oceanic Anoxic Events (OAEs) during the Paleozoic and Mesozoic periods. Studies of terrestrial ecosystems and climate change during the OAEs will also be included.


Theme 4

Linkage of Cretaceous solid earth dynamics, greenhouse climate, and response of ecosystems on land and in the oceans in Asia (IGCP679 Joint Session)

Convener: Takashi Hasegawa (Kanazawa University), Gang Li (Nanjing Institute of Geology and Palaeontology)

This session is a collaborative session with IGCP 679. Discussion on linkage of Cretaceous ecosystems and paleoenvironments on land and in the oceans based on the paleontological, geochemical and other point of view is welcomed.


Theme 5

Evolution of reptiles including birds

Convener: Soki Hattori (Fukui Prefectural University)


Theme 6

Secondary aquatic adaptation of tetrapods

Convener: Yasuhisa Nakajima (Tokyo City University)


Theme 7

Diversity of non-tetrapod vertebrates

Convener: Shinya Miyata (Josai University), Yoshitaka Yabumoto (Kitakyushu Museum of Natural History and Human History)


Theme 8

Fossil record of mammals and their allies

Convener: Yuri Kimura (National Museum of Nature and Science)


Theme 9

Diversification and evolution of vascular plants

Convener: Toshihiro Yamada (Osaka Metropolitan University), Yondong Wang? (Nanjing Institute of Geology and Palaeontology)

Fossils provide direct evidences on innovations in plant body plans, as well as on the background in which these innovations had been happened. We will discuss on them in this session. Related evo-devo papers are also welcomed.


Theme 10

Mesozoic terrestrial biota in the realm of Angiosperm diversification

Convener: Harufumi Nishida (Chuo University), Ge Sun (College of Paleontology, Shenyang Normal University)

In this session, we will focus on the floristic changes during the Mesozoic including the rise of angiosperms. We will also welcome contributions on the Mesozoic terrestrial biota and environments which should have been influenced by floristic changes.


Theme 11

Cenozoic floristic evolution in Asia

Convener: Atsushi Yabe (National Museum of Nature and Science), Tao Su (Xishuangbanna Tropical Botanical Garden)

Origin of floristic diversity in the Asian region has been greatly documented for the past decade based on Cenozoic paleobotanical studies in new and known fossil sites. We would like to discuss the latest knowledge on paleobotany, phytogeography and paleoclimate to synthesize our understandings on floristic evolution in the Cenozoic of Asia.


Theme 12

Diversity change and evolutionary history of radiolarians

Convener: Noritoshi Suzuki (Tohoku University), Zhang Lanlan (South China Sea Institute of Oceanography, Chinese Academy of Science)

This session is ready for any topics on radiolarians and advanced studies mainly based on radiolarians. Oceanographic, paleoceanographic and geotectonic topics as well as new technologies like machine learning are much welcomed.


Theme 13

Foraminiferal biology and paleontology for understanding life, environmental histories and biostratigraphy

Convener: Takashi Toyofuku (Japan Agency for Marine-Earth Science and Technology), Hiroki Hayashi (Shimane University), Hiroki Matsui (Akita University), Haruka Takagi (Chiba University), Akira Tsujimoto (Shimane University)

Foraminifera are important microfossils that have supported the development of the Earth Science as excellent index and facies fossils, as they change their distribution in response to the microenvironment and their occurrence are well documented. Especially in the Asian region, where population growth and industrial development are rapid, coastal environmental changes and the effects of land use changes on the ocean are important issues that must be monitored to make a safe marine environment, and foraminifera are excellent environmental indicator organisms. In this session, we would like to include in the scope the ecology and biology of foraminifera, as well as their applications as indicators of such geologic times and environments.


Theme 14

Molecular palaeobiology and molecular evolution

Convener: Kazuyoshi Endo (University of Tokyo), Yanhong Pan (Nanjing University)

This session explores multifaceted aspects of molecular palaeontology and molecular phylogeny, including molecular fossils, biomineralization, molecular phylogeny of fossiliferous taxa, resurrection of ancestral genes, and (paleo-)evo/devo of multicellular organisms. Presentations on any topics related to this field will be welcome.


Theme 15

Geochemical proxies discovering palaeoecology, palaeoenvironment, and their interactions

Convener: Kazuyoshi Moriya (Waseda University), Kotaro Shirai (University of Tokyo)

Geochemical proxies have helped to discover ecological interactions and “coevolution” between life on Earth and its environment. Recent advancement in analytical instrumentation have allowed us to disclose faint and/or hidden signatures of ecosystem preserved in fossils and rocks. Conventional techniques hitherto established can also be powerful tools when they are applied to unexamined taxa, physiological pathways, ecological aspects, and/or elements. This session focuses on any subject of geochemical proxies in palaeoecology, palaeoclimatology, and palaeoceanography. Topics on proxy and/or instrument development are also welcome.


Theme 16

Tomographic techniques and computer-aided visualization in palaeontology

Convener: Soichiro Kawabe (Fukui Prefectural University)


Theme 17

Analytical approaches for evolutionary morphology

Convener: Takao Ubukata (Kyoto University)

Numerical methods are of growing importance in morphological studies of fossils. The past several decades have seen the introduction and development of many analytical techniques aimed at addressing palaeontological questions related to morphological data. This symposium will focus on the practical aspects of morphological analysis and will cover a broad range of methodologies such as morphometrics, allometry, theoretical morphology, morphospace analysis, disparity analysis, analysis of evolutionary rates, phyllogenetic analysis, functional morphological analysis, and so on.
