I should start a Tumblr.
H.W. Menke, field assistant to Elmer Riggs, discovered the Brachiosaurus in Colorado in 1899, returning to excavate it in 1900. He lay on the ground next to one of its arm bones to convey its unprecedented size, creating a humerus photo.
When James "Dinosaur Jim" Jensen discovered Supersaurus (also in Colorado) he posed next to its shoulder blade so others could get a sense of its size relative to a coffee mug.
I believe this was the photo for which the act of lying on the ground next to giant dinosaur bones is now sometimes called "a Jensen" or "Jensening".
The French team that uncovered Sarcosuchus (NOT A DINOSAUR, but instead the largest known crocodile) were lining up behind its skull to show how long the full animal might have been.
Sexy paleontologist Mike Taylor posing in front of a cervical (neck) vertebra from Supersaurus. This is the longest-known vertebra of anything ever.
And sexy Mike Taylor posing in front of a purely speculative vertebra from Amphicoelias. Mike Taylor is trying to replace the "Jensen" with the "Mike Taylor Smouldering Recline Scale Unit" (MTSRSU) as a standard unit of fossil bone measurement.
"Draw me like one of your French fossils." — Jose Ignacio Canudo, in front of a femur from that new Argentine titanosaur that was all over the news.
Pablo Puerta, also next to the new Argentine titanosaur, is not the one currently crushing those wooden pallets.
And here's Diego Pol, one of the lead paleontologists for that new Argentine titanosaur. Apparently everybody on the team wanted a shot at this photo. (I don't blame them.)
