Angel sharks are sharks, but with their peculiarly flat body they rather resemble rays. An international research team led by Faviel A. López-Romero and Jürgen Kriwet of the Institute of Palaeontology has now investigated the origin of this body shape. The results illustrate how these sharks evolved into highly specialised, exclusively bottom-dwelling ambush predators and thus also contribute to a better understanding of their threat from environmental changes. The study is published in the journal Scientific Reports.
A llama carved from a spondylus shell and a cylindrical laminated gold foil object were the contents of a carved stone box -- an offering -- found at the bottom of Lake Titicaca, according to researchers from Penn State and the Université libre de Bruxelles, Belgium. The offering, found near an island in the lake, was not located where others had found offerings in the past.
Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor.
Researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences showed that the alpine flora of the Hengduan Mountains has continuously existed far longer than any other flora on Earth. They also illustrated how modern biotas have been shaped by past geological and climatic events.
Paleontologists have described in the Journal of Vertebrate Paleontology a large owl that killed medium-sized mammals with its feet and claws some 55 million years ago.
Most of the hulking sandstone boulders -- called sarsens - that make up the United Kingdom's famous Stonehenge monument appear to share a common origin 25 kilometers away in West Woods, Wiltshire, according to an analysis of the stones' chemical composition. The findings support the theory that the stones were brought to Stonehenge at around the same time,
Alarming results from a 2019 survey of well-known archaeological site Ageröd reveal drastic bone and organic matter deterioration since the site's initial excavations in the 1940s, suggesting action is needed to preserve findings from Ageröd and similar sites, according to a study published July 29, 2020 in the open-access journal PLOS ONE by Adam Boethius from Lund University, Sweden, and colleagues.
A research team led by Dr. Alida Bailleul from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences has proved that remnants of bird ovaries can be preserved in the fossil record.
The animal was approximately 10 cm long and lived more than 130 million years ago in what is now the state of Minas Gerais. Its morphology differs from that of all other known lizard species.
Unlike businesses or governments, organisms can't go into evolutionary debt -- there is no borrowing one's way back from extinction. This can lead to seemingly irrational economic choices that suddenly make sense when viewed as a multiplicative, evolutionary process.
