A reconstruction of the Mahantango Formation

[Bringing Fossils to Life]

I just finished a reconstruction of the Mahantango ecosystem, based off of fossils I have found at corresponding sites. This certainly does not cover all species in this formation, but many of the most prominent (Sorry no Dipleura, haven't done that one yet). I recently learned about Striacoceras and re-identified many of my orthocerids as this obscure genus. Striacoceras is the brown orthocone in the background. I included two crinoid genera, (left to right) Ancyrocrinus and Botryocrinus. an Eldredgeops searches for prey. There are several Mucrospirifer brachiopods, some Orthonota bivalves, a couple ammonoids (Tornoceras and Agoniatites), and some Pleurodictyum coral. In the distance, a shoal of Bactrites drifts. This is one of my first entire ecosystems.

Also, are there any Michelinoceras telamon in the Mahantango, or any M. sublatum? Are the sutures always visible, or is the shell sometimes smooth like Bactrites? If so, how to tell crushed specimens apart?

Where are the gastropods?

Sorry! As I said, this is not complete. I will post a gastropod as soon as I make one.

Here is the picture above, but with some Cyclonema Gastropods. Now that I think of it, I don't know how I forgot the gastropods - they're so common!
