Do you have an ISBN for that book? The frogs in the coal caught my interest. From studying amphibians, I know that some species burrow into the
ground and enter into a very reduced metabolic state. Some do not re-emerge for years.
There are mudskippers in Africa that come up every time it gets flooding rains, they burrow about 3 feet or so down and their heart beats, I think it
was, once every three or four days, or maybe it was once a week or month? I know when alligators sleep their heart beats once an hour or so. Frogs
also do this when they hibernate in the midwest. Doubt that a bird like that could stay alive inside a limestone rock for millions of years though.
