Your information regarding these unusual tracks and eggs piqued my interest enough to extract the specimen from the back of the fridge - where it was ensconced behind a jar of mayo and a gallon of milk. Unfortunately, because my daughter brought the specimen to me from San Diego, the specimen is out of context, and except for the immediate matrix surrounding the specimen, there is no data available for the locality in which it was found.
Chemical analysis shows similar content to the previously cited eggs and tracks - milk chocolate.
The skin surfaces are intact and appear to be consistent with extant elephants - appears wrinkled rather than bumpy or scaly. The neck is a mere 3 cm long, with an overall height of 11 cm from the top of the skull to the bottom of the feet. There is a slight inaccuracy between this artist's reconstruction and the specimen, however. Just thought I'd add my info on similar trackways and eggs. I recently purchased part of a tyrannosaurid trackway, identified as T. rex.
