Cambrian explosionmacroevolutionpaleobiology
Charles Marshall studies the history of biodiversity and the tempo of evolutionary events, including the Cambrian explosion. His work integrates the fossil record with evolutionary theory and comparative genomics.
Neil Shubin is best known for co-discovering Tiktaalik roseae, a 375-million-year-old fish that documents the evolutionary transition from aquatic to terrestrial vertebrates. His research bridges paleontology and developmental biology.

taphonomypaleoecologypaleoanthropology
Kay Behrensmeyer is a pioneer of modern taphonomy — the science of how organisms become fossils. Her long-term research in the Turkana Basin, Kenya has significantly advanced our understanding of hominin evolution and African paleoenvironments.
Derek Briggs is a world authority on Cambrian Burgess Shale-type faunas and the processes of exceptional fossil preservation. His research has transformed understanding of Cambrian animal diversity and early animal evolution.
Mike Benton is one of the world's leading vertebrate palaeontologists, with major contributions to understanding mass extinctions, the Triassic recovery of life, and the early evolution of dinosaurs. He has authored influential textbooks used in paleontology courses worldwide.
Roger Benson investigates macroevolutionary patterns across deep time, particularly in tetrapods. His work has illuminated the evolutionary dynamics of dinosaurs, marine reptiles, and patterns of body size change across hundreds of millions of years.
Christopher Beard has discovered and described numerous fossil primates from Asia and North America, significantly reshaping understanding of primate origins and early anthropoid evolution. His fieldwork in Myanmar and China has yielded important early anthropoid specimens.
Emily Mitchell applies quantitative and spatial analytical methods to understanding Ediacaran organisms — the enigmatic multicellular life forms that preceded the Cambrian explosion. Her work bridges paleontology and modern ecology.
How researchers advance our understanding of life's history
Understanding Evolution
Paleontologists document evolutionary change in the fossil record. Track how organisms transform over millions of years. Provide evidence supporting evolutionary theory and revealing mechanisms of evolutionary change.
Dating Earth
Use fossils and radiometric dating to establish the age of rocks and time scales of geological events. Calibrate the geologic time scale. Understand Earth's chronology back billions of years.
Reconstructing Ecosystems
Analyze fossil assemblages to understand past environments and community structure. Interpret ancient climates, sea levels, and habitat types. Reconstruct complex food webs from geological evidence.
Biodiversity Patterns
Study how biodiversity changes through time. Document extinctions and diversifications. Understand factors affecting species survival. Provide context for modern conservation challenges.
Organism Function
Use biomechanics and functional morphology to understand how extinct organisms moved, fed, and behaved. Reconstruct paleobiology of ancient species. Bridge anatomy and behavior.
Climate History
Analyze fossils and rocks to understand past climate changes. Identify patterns in climate transitions. Provide baseline for understanding current climate change impacts.
