Can macroscopic organisms of this size really be called "consumers"?

The comma is "decades, however" should be a period. As it is, it looks on a run-on sentence. "replaced" should not be capitalized.

I look forward to seeing further development on this.

This does bring up the point, should the ancestors diet be changed? And if so, what would the better term be?

Herbivore? Microbivore? Both?

Would detritivore work?

I went with Microbivore
