Jurassic ecosystem
PhysOrg.com [USA], March 2, 2012
Scientists are uncovering a beautifully-preserved ecosystem from around
a Jurassic hot spring, helping fill a gap in the fossil record of more
than 300 million years. Discovered in Patagonia in southern Argentina,
the San Agustin geothermal deposits include animals, plants, fungi and
bacteria, preserved in three dimensions and with their internal
structure largely intact. The fossils date from around 150 million years
ago, and formed around an area where water heated deep underground rose
to the surface. This is the first time a hot-spring habitat from the
Mesozoic era has ever been discovered.

Chinese fossils bear evidence of Jurassic-era fleas
Xinhua News Agency [China], 2012-03-01
Fossils discovered in north China have revealed the existence of giant
fleas dating back to the mid-Jurassic era, when dinosaurs still lived on
Earth, according to a report published Thursday on the website of the
scientific journal Nature. The fossils date back as far as 165 million
years, making them the oldest known evidence of fleas, according to
Huang Diying, a scientist conducting research on the fossils.
