Is the most pronounced crater in Lamarck, known as Lamarck B, a Concentric Crater? Take a look at the Hi-Res scan of Lunar Orbiter 4's photograph LOIV-168-h1.

Possible Concentric Crater: Lamarck B.- DannyCaes Nov 2, 2009
Nomenclature
- Named for Jean-Baptiste Pierre Antoine de Monet, Chevalier de Lamarck (August 1, 1744 – December 28, 1829), a French soldier, naturalist, academic and an early proponent of the idea that evolution occurred and proceeded in accordance with natural laws. Lamarck is usually remembered for his belief in the inheritance of acquired characteristics, and the "use and disuse" model by which organisms developed their characteristics.
- This name was assigned in the Rectified Lunar Atlas (1963), based on Earth-based photos of the libration zones, and approved by the IAU in 1964, to which it was described as a 96 km diameter crater centered at 22.5°S, 70.0°E, and formerly regarded as the southern part of Darwin.
- In preparing its initial long list of farside names, the IAU Working Group for Lunar Nomenclature was initially unable to find evidence in space-based overhead views of a significant crater at that location, and announced at the August 1970 IAU meeting its plan of deleting the 1964 approval and reassigning the name to a farside crater now known as Hopmann.
- Subsequent to the 1970 meeting, Whitaker produced space-based images of the crater he had intended to name. The name was reapproved in Menzel, 1971 as representing the crater at "22°S, 70°W".
- The version of ACIC map LMP-3 from October, 1970 (prepared before the final IAU farside list had been published) labels Lamarck at the proposed changed location (the current Hopmann).
