We picked up a button when we arrived and on the brim of the button reveals the group that we will be part of. I subconsciously just chose the button of a upper mandible of a felid. Bones, bones, bones. So we were assigned to Group #2 for a behind-the-scene tour. But before the tour, we gathered at Akeley Hall of African Mammals to mingle. There was, of course, wine and cheese. Oh yea, it's classy like that.
Led by an ichthyologist and an entomologist graduate students, the first stop for this group was a classroom-like setting where we were treated to amber, flies, ants and stained fishes. Sweet. I got to hold a piece of Baltic amber that encases a pair of flies that are still in the heat of copulation. Pretty rad. There was also amber that encases a species of previously undescribed ant. That guy has a massive pair of mandibles. We also spent some time looking at stained fishes under the microscope, although the staining technique itself is sufficient to show the complexity of fish osteology. "Fish bones are jigsaw puzzle from hell". Yep, that pretty much sums it up along with articulating a snake. The staining technique uses red dye to color the bones and blue dye to color the cartilage. Here's a writeup on how to prepare a stained fish Hidden Blades, Glowing Scorpions and Bug Genitalia: Great Science Images From the American Museum of Natural History.

|Vance loves ants. So he's particularly excited.|

As the behind-the-scene tour ends, we were ushered back into the Akeley Hall of African Mammals and got to spend more time mingling and taking in the new photo exhibition. There was a photo exhibit of Chilecebus (Chilean Monkey), an extinct primate and the only specimen of its kind ever found. Using a CT scan, the researchers were able to look inside the skull of Chilecebus to reveal its brain size and the shape of its head's semicircular canal.

Brownie points to Denton Ebel, the Curator-In-Charge of Department of Earth and Planetary Sciences for walking us through the exhibition and explaining to us in depth the "Warhol" meteorite photo exhibit. And also thanks for all the jokes "It's perfectly round, just like tears of astronauts in space ... because they missed home". Oh yes, I forgot about the swag. This time we were ushered away with some postcards from the photo exhibition and also a scorpion sucker! Hmm ... I dunno, I don't think I am gonna eat THAT. But thanks for another great tweetup, American Museum of Natural History! Looking forward to the next one.
