The plaque describing this fossil has fairly minimal information. Wikipedia, however, has a nice article on Diplodocus, which includes a public domain image of the replica skeleton being presented to the trustees of the British Museum of Natural History in 1905.

Given the limitations of physical media, museum labels and plaques will always be small, and will often be out of date. Wikipedia, of course, can be kept current, and anybody can contribute.
So, the trick is to link the physical object to the Internet. This is now trivial thanks to mobile tagging. By pointing a mobile phone with a camera at a 2D barcode, one can go from physical object to web site.


Now that the iPhone has applications, imagine creating an application that read these barcodes. Kevin Chiu at Columbia has a made one, and there are others out there. Museums could build on this, brand it with their logo, and greatly enhance visitor experience.
Wonder if anyone is doing this...?
