ASU is reporting that "High-resolution photos (taken by a UA camera) of lava flows on Mars reveal coiling spiral patterns that resemble snail or nautilus shells. Such patterns have been found in a few locations on Earth, but never before on Mars. The discovery, made by Arizona State University graduate student Andrew Ryan, is announced in a paper published April 27, 2012, in the scientific journal Science.
Snail shells coil in response to a lopsided protein gradient across their shell mantles, finds new research. In contrast the shell mantle of limpets, whose shells do not coil, have a symmetrical pattern of the protein Decapentaplegi...
A researcher has spotted lava flows shaped like coils of rope near the equator of Mars, the first time such geologic features have been discovered outside of Earth.
Resembling corkscrew snail shells, these interesting patterns are actually rare lava flows seen for the first time on Mars.
Lava flows coiled like snail shells have been found for the first time on Mars - and they're bigger than anything similar on Earth. read more
