Pyritized Triarthrus trilobite from the Lorraine Group of NY showing preserved legs and antenna.  There are only a handful of localities in the world that produce soft bodied preservation on trilobites.

Dunkleosteus terrelli boasted a 20-foot-long body covered with bony plates of armor. Fossil records indicate that this huge fish, one of the first large jawed vertebrates in the ocean, was an aggressive predator.
The razor-sharp edges of bones in this animal’s jaws served as cutters. As they rubbed against each other, the opposing jaw blades acted like self-sharpening shears. These bones continued to grow as they were worn down by use.
Dunkleosteus is located in the Museum’s Hall of Vertebrate Origins.

AMAZING DOPPLER RADAR IMAGE:FROM OUT OF THE MISSISSIPPI, MAYFLIES EMERGE TO MATE AND DIE
Via evolutionary biologist Jerry Coyne's Why Evolution Is True blog [July 22, 2014]
What you’re seeing is a Doppler radar loop from the Lacrosse, Wisconsin office of the National Weather Service.  
What the radar saw for 90 minutes was a massive mayfly emergence on June 23.
Probably the giant mayfly, Hexagenia limbata.

On Saturday evening, June 23 2012, a massive mayfly emergence occurred along the Mississippi River beginning just after 9 pm. By late evening, mayflies were swarming in La Crosse, La Crescent, and points up and down the river. While the emergence of mayflies from their river bottom mud dwelling can occur at various times through the warm season, this particular event was one of the best seen on radar yet. 
In the radar time lapse loop from 9 pm to just after 1030 pm, the yellows and oranges indicate a large magnitude of airborne mayflies. 

Go here to see another amazing radar loop showing part of this swarm of mayflies being carried off by the wind at altitudes as high as 3000 feet!
