Nanopusis an ichnogenus- evidence
for a creature based only on the
traces it left, such as droppings,
burrows or, in this example,
footprints. The shape of the
prints differ between the
manus(the.'hand' of the
front limb) and the pes
(the 'foot' of the rear limb).
Particularly well-known prints ascribed to the
ichnogeneraMatthewichnusand Nanopus, along with
footprints and track ways made by many other vertebrates
and invertebrates, are known from sites such as the Union
Chapel mine of Walker County, Alabama, USA. These
fossils are dated to the Westphalian (Moscovian) part of the
Late Carboniferous Period, just more than 300 million years
ago. Studies of these and other prints, including their
spacing and progress pattern, the way the toes splay, and
. associatedtail drags, give clues to
the walking and swimming abilities
of tetra pods such as Nanopus,
Limnopusand Matthewichnus
from Carboniferous times.
