Was it moving? It looks a lot like a euglyphid, shelled amoebae that pull themselves slowly with filopodia when they travel at all.

It is very unlikely to be a trematode egg without the cap (opercula).

Reasons why this may not be a trematode egg:
1. Hatched trematode egg shells retain their dark brown/ golden color.
2. Trematode eggs are very dense and rapidly sink to the bottom of a liquid sample. This makes them difficult to find unless a sedimentation is performed and the sediment is scanned for the ova. Most trematode eggs are not found on standard fecal flotation test because they are more dense than the high-density flotation solutions; hence, why fecal flotation is a poorly-sensitive diagnostic test for trematode (fluke) infections.

As actinophrys says, it's the shell of a Euglypha (a dead one, I think).
