The fish fossils are amazing specimens from the Green River formation.  Although the fossils themselves are similar, the rocks in which they are embedded are not uniform in size or weight. We are not able to pick particular sizes because there are so many random variations due to how they were cut out of the larger slab. However, the following provides a minimum/maximum range for size and weight of the fossils.

Size: 3″ x 5″ up to 6″ x 9″

Weight: 4 oz to 2 lbs
