For questions or comments please contact the course instructor Carl-Georg Bank [email protected] ESS261 Journal, volume 1 (2021) i Introduction from Asia is outlined by Yuan, where fossils from Chengjiang rival those found from the The Earth system -- the lithosphere, atmosphere, Burgess Shale. All of the aforementioned hydrosphere, and biosphere -- has evolved over contributions have described discoveries that billions of years and is the home for all known have played significant roles in the life, including humans. It is a delicate home, it understanding of life and evolution on Earth and is a fascinating home, and it challenges us to will continue to do so for centuries to come. better understand its balances. This course took us on a journey through the 4.567 billion years 2. Our understanding about past life is still of Earth's history, and the papers in this journal growing. This section includes various papers mark the culmination of student work. The relating such new discoveries and discussing journal is split into four parts: their significance for understanding life’s many changes over the eons. 1. Lagerstätten have been crucial in not just Relationships between form, function, producing significant fossils, but have also and phylogeny are a common theme underlying advanced our knowledge of the Earth system as these papers, nicely capturing the classic trifecta snapshots in time. These sites contain of causal phenomena in evolution. This is exceptional numbers of fossils and may also exemplified by contributions by Cheng, Gupta exhibit exceptional quality preservation which and Han, and Mooney and Osterling Arias, warrant their protection for years to come. These highlighting bizarre morphologies in different discoveries often become UNESCO World groups of dinosaurs and the efforts that have Heritage sites due to their importance to science been made to understand their origins and and their contributions to our body of diversity. Similarly, Patterson and Panasiuk knowledge. provide a deep dive into the evolution of Several famous Lagerstӓtten from North dinosaur feathers and hypotheses for their America are described in great detail including evolution. the unique and bizarre organisms from the The papers also span the full range of Burgess Shale located in the Canadian Rockies taxonomic diversity encountered in the fossil highlighted by Bormann and Merrick.

On the East to that afforded to dinosaurs.

Choi and Fortune discuss a new Point, Newfoundland. Canadian discovery: the earliest fossil Some of the most important Lagerstӓtten occurrence of a neglected group of organisms – found in Europe are from Germany, illustrated the fungi. by Al Raisi and Eaton-Tessier who focused on Finally, many articles emphasize the the Devonian fossils found in Bundenbach, and utility of new methods for interrogating the through significant discoveries such as the first fossil record. In particular, Chen examines bird Archaeopteryx at Solnhofen by Guillerez. several case studies involving hydrodynamics in Many discoveries have been made in South the fossil record. She shows that some fish body America, but a unique site containing differerent shapes have evolved repeatedly while others types of fossilized animals including pterosaurs were unique. Similarly, Walker and Moya walk discovered in the Santana formation from Brazil us through the study of colour in the fossil is reviewed in a descriptive contribution by record, as revealed by preserved pigment- Murphy.
