Extraordinary Pseudoangustidontus!!! - Fossilised animal - Pseudoangustidontus duplospineus (Van Roy & Tetlie, 2006) Origen - 9 cm - 8.5 cm (No Reserve Price)

The spectacular frontal appendage of Pseudoangustidontus. This structure allowed Pseudoangustidontus to feed, filtering or sifting and trapping the microscopic organisms it consumed (plankton). Pseudoangustidontus is an extinct genus of filter-feeding radiodont belonging to the family Hurdiidae that lived 480 million years ago during the early Ordovician period. This animal was described as the oldest known fossil and the largest animal known to have been a filter feeder.

The extraordinary preservation of the fossil allows for detailed observation of the delicate structures of the filtering appendage. A specimen worthy of a museum.

Plastic supports included.

The deposits of the Fezouata formation, near the Moroccan city of Zagora, are providing a rich and diverse record of fossils with extraordinary preservation, up to soft tissues or soft-bodied animals being recorded fairly frequently. This type of preservation is similar, although later in time, to that of the famous Burgess Shale site (Canada).

These are fossils dating from between 480 and 472 million years ago. At that time, Morocco was an ocean and was located over the South Pole.
