And will feature three talks. Learn about the evolution of life and climate with U-Pb geochronology in the early Paleozoic/EoCambrian (Nelson, Carleton Univ); about global climate in South Africa during the Karoo igneous events of the early Mesozoic (Gaynor, Princeton University); and a cautionary tale about inferring ancient temperatures from distributions of quartz with rutile (Tailby, American Museum of Nat. History, NYC). The meeting will be carried live on Zoom beginning at 8 PM on 16 Nov. Meet up with friends and colleagues beginning at 7:30. Members will shortly receive an invitation with the Zoom information. Non-members are encouraged to attend. Contact Michael Ackerson (ackersonm[at]si.edu) for the Zoom link if you do not have it.

Happy Birthday @USGS! ⛰️💧🪨🌋🗻
Got a a chance to hold a cast of the mandible or lower jaw of Spinosaurus at the new Sereno Fossil Lab of @UChicagoBSD. I keep forgetting how massive Spinosaurus was! #Dinosaurs #Paleontology #FossilFriday
Do other planets have leap years?
Yes! Leap years happen because a planet’s orbit around the Sun (year) and rotation on its axis (day) are not perfectly in line. This is true of almost every other planet in our solar system.
Are leap years really that important?
Leap years are important so that our calendar year matches the solar year. For example, say July is a warm, summer month where you live. If we never had leap years, in a few hundred years, July would take place in the cold winter months!
