A large, 7m deep depression with a curved limestone scar at the back and possible digs at the base. (This may not have been documented before because the field it is in often has or had a herd of cows with a bull. There are a number of features that may merit a closer look. See 360° aerial photo dated 1/4/2018 on this page.)
