Co-evolution of geological and biology from a mineralogical perspective
• Earth's surface harbours at least 5809 known minerals, but when Earth first formed 4.65 billion years ago, it had about 420. Moreover, what is common on the surface today was uncommon then. Many rocks and minerals have come into being while others have become extinct. • The overall increase...Walcott, Rachel

Early Eocene fossil illuminates the ancestral (diurnal) ecomorphology of owls and documents a mosaic evolution of the strigiform body plan
We describe a partial skeleton of a fossil owl (Strigiformes) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Ypresiglaux michaeldanielsi, gen. et sp. nov. is one of the most complete specimens of a Palaeogene owl and elucidates the poorly known ecomorphology of stem group Strigiformes....Mayr, Gerald ; Kitchener, Andrew C

Oldest fossil loon documents a pronounced ecomorphological shift in the evolution of gaviiform birds
We describe a stem group representative of Gaviiformes (loons or divers) from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK). The holotype of Nasidytes ypresianus gen. et sp. nov. is a partial skeleton including the mandible and all major limb bones. The new species is the oldest unambiguously identified...Mayr, Gerald ; Kitchener, Andrew C

Middle Jurassic fossils document an early stage in salamander evolution
Salamanders are an important group of living amphibians and model organisms for understanding locomotion, development, regeneration, feeding, and toxicity in tetrapods. However, their origin and early radiation remain poorly understood, with early fossil stem-salamanders so far represented by larval or incompletely known taxa. This poor record also limits understanding of...Jones, Marc E H ; Benson, Roger B J ; Skutschas, Pavel ; Hill, Lucy ; Panciroli, Elsa …

The earth: a biography of life: the story of life on our planet through 47 incredible organisms
It is difficult to conceive of the vast scale of the history of life on Earth, from the very first living organisms sparking into life in hydrothermal deep-sea vents to the dizzying diversity of life today. The evolution of life is a sweeping epic of a tale, with twists and...Pancorili, Elsa
