The only differences apparent to me are the title, the price, and the
distribution. When _The Jehol Biota_ was published in 2003, it sold for
$150 US plus shipping and handling
Except if you bought it at the 2nd International Palaeontological Congress,
for 50 $. Mwa ha ha ha haaaaah...
Let me repeat that this book contains lots of very nice large color photos.
No comparison to the excruciatingly coarse-grained, often b&w pictures in
the primary literature.
