He conducted the research at the Royal Ontario Museum while pursuing a doctoral degree in the University of Toronto’s department of ecology and evolutionary biology. For the new investigation, the researchers examined around 150 fossils collected by Royal Ontario Museum during expeditions between 1975 and 2000. The carapace folded over Odaraia’s limbs, so it may have been unable to walk on the seafloor, according to the Royal Ontario Museum.

A Fossil Mystery, Solved by a SpinEssexella fossils date back to the Carboniferous period, when northern parts of Illinois hovered just above the equator. Essexella fossils are composed of two structures — a textured, barrel-shaped region and a smooth bulb. “It looked like the bottom of an anemone,” Dr. Plotnick said. Dr. Plotnick, Dr. Hagadorn and their team redescribed Essexella as an ancient anemone last year in the journal Papers in Palaeontology. Dr. Plotnick posits that these animals once lined the floor of the Mazon Creek estuary.

Prints of photographs from Madonna’s wildly popular 1992 coffee table book “Sex” will be available for purchase for the first time at Christie’s New York this fall, part of ongoing projects to mark the 30th anniversary of the controversial publication. In October, over 40 prints first published in “Sex” will go up for sale as part of a special standalone auction. “Thirty years on, ‘Sex’ is still somewhat controversial, but it still reads as a very body-positive, sex-positive book,” Himes said. “Sex” also featured Madonna’s then-boyfriend, rapper Vanilla Ice, and stars like supermodel Naomi Campbell and socialite Tatiana von Fürstenberg. The prints will go on display at Christie's galleries in London, Paris and New York before the October auction.
