I found this fossil while doing my fieldwork in limestone area. Description below may help to identify it.

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

    $\begingroup$ changing the title to indicate it is a marine fossil will help get more traffic. But you may have to take it to a museum, Cambrian fossils can be particularly difficult to identify quickly, since they are so different than things alive today. you need someone vert familiar with Cambrian fossils. $\endgroup$

1 Answer 1


it looks like a gastropod, as there are no septa. Maybe it is Malayaspira, which is Ordovician
