The Dry Dredgers

An association of amateur geologists and fossil collectors. Established 1942; based out of Cincinnati, Ohio, USA. The Upper Ordovician is our specialty!

Just implemented very basic megalograptus dueling behavior...its just basic snapping damage and fighting for now, but I plan on adding grappling mechanics for when two lock arms and end up wrestling each other (yes I got my ass handed to me in the 2nd half)

It's rare for me to have fossils from the U.S. West Coast for #FossilFriday, so I’m excited to share Olenellus clarki! This trilobite was found near San Bernardino, California, and lived 512 million years ago during the Cambrian Period. 🇺🇸

refining how i want to reconstruct dunk's face and plates
not skeletal but plates are mostly visible, but somewhat flush with the surrounding soft tissue
using bony fish as a guide

MY OWN DUNKLEOSTEUS THREAD!!
there has been a decent amount of change to this animal and i feel i might explain how to reconstruct this animal and the reasons i reconstruct it the way i do!!

Here the result of the last formation stream of 2024. Over the course of 6 hours we explored the many organisms that inhabited the reefs of the Whitewater formation.

What invasive species were changing communities.... over 400 million years ago? Dr. Alycia Stigall talks about this and her research in a recent interview with GEOgirl.

The dunk has done more than shrunk: New paper discusses everything you want to know about reconstructing #Dunkleosteus. Other highlights include body plan evolution in #arthrodires and future research directions on their #biomechanics and #metabolism.

I’m sort of lagging behind the days but what can you dooo

Coming up with color schemes that give mollusk but are still unique is the biggest challenge for me
