 Description:
Approximately seven years ago a number of Carboniferous fish from
Siberia appeared on the market for a year or two. Then they suddenly
became unavailable. So I was pleasantly surprised to discover three
specimens of two different fish at the Tucson Gem and Mineral Show
this February. With the species name being minimus, it is
obvious these were small sized fish. The detail is very good, showing
the scales,
head and tail features. Now here is a rare treat from a distant
and obscure locality. The paleoniscoids were the first ray-finned
fish, a feature readily seen here. Some 40 or more families appeared
during the Carboniferous
and Permian Periods.
