Asaphus kowalewskii
Specimens of the trilobite Asaphus kowalewskii often have surface abrasions or significant restoration, but this specimen is high-grade with no abrasions and less than 5% restoration.
The beautiful amber-colored exoskeleton is also a favorite point.
64.6 x 42.2 mm, 340g
I think I obtained a specimen in good condition at a very low price at an auction.
