Bamboo pipelines in Szechwan province, China

Bamboo pipelines, nearly 3000 years old, are still in use in Szechwan province, China. Some of the lines transmit natural gas to salt evaporator houses for fuel in the dehydration process of making salt from brine.

Baculites compressus

Baculites compressus. Say, from the Cretaceous of the South Dakota. 1. A young shell preserving the early coils. The living chamber occupied about one half the length of the shell. 2. A specimen of the same size as the last but with the outer shell broken away revealing the sutures - the outer edges of the septa. Note the variations in the sutures from the apex of the shell 2 to its wide end and on through the progressively layer shells as shown in 3, 4, 5, and 6, which represents the condition of the suture in the adult shell.
