Location: NW Perlis, Malaysia (Setul Formation). Hilly Area.

My Observation:

  1. Have a curly shape
  2. It have line and look like a suture
  3. Does not have visible feature of cephalopod like septa and chamber.
  4. It can be found between layer of stromatolite
  5. Other fossil found nearby: gastropod, cephalopod and brachiopod (most of this fossil already have been damage but the shape still good and can easily identify it.

Size of the coin: 2.2 cm.

I hope this information is helping to identify the fossil. Thanks.

Plan View of the fossil and its has curly shape

Look like a suture

The "suture" still can be seen from the inside
