Uhligia
Encyclopedia
Uhligia is a Lower Cretaceous (Barremian
) ancylocerid ammonoid cephalopod initially found in Germany.
Uhligia, named by Koenen, 1904, has the general form characteristic of heteromorph ancyloceratids. The early part is more or less straight, then sharply bent, followed by a second straight shaft and a final hook. Ribs are fine, weak, and irregular, lacking tubercles; slanted in the early part, straight in the later. Uhligia differs from genera like Ancyloceras
and Aspinoceras
in lacking the open coil in the early stage.
