Dry Dredgers Field Trip
May 26, 2007
Hueston Woods, Ohio
Fossils Found at First Site
Brachiopods
By far, the most common fossil found in this rugged environment was the hearty Brachiopod.
Most of the Hebertella
found were on the surface of rocks.
Also found only on rock surfaces was the interesting, slightly
less common, Plaesiomys subquadratus
As mentioned earlier, lots of rocks were covered with Strophomena
Brachiopods.
Along with the Strophomena, as shown in the shot below, were Lepidocyclus
and Rafinesquina.
When found, the Brachiopopod Eochonetes were
found in abundance.(below)
Trilobites
A few fragments of the common trilobites, Flexicalymene
and Isotelus, were found, but
no whole ones. Here's a picture of one of the Isotelus
fragments.
Corals
Two main types of coral were found that day at site 1. The
first is a solitary Horn Coral, called Grewingkia.
The second type of coral was the colonial coral, Tetradium.
Certainly, other types of coral can be found on this site, but are not pictured here, such as the encrusting coral, Protaraea.
Ichnofossils (Trace Fossils)
Some interesting worm burrows were seen at site 1. The next 3
pics show particularly large and abundant worm burrows called Diplocriterian.
Other interesting burrows show a vast branching pattern across
large slabs and other continuous groups of rocks.
The scenery at the first site, as you can tell from the
earlier photos was breath-taking and there were lots of wildlife to observe,
such as salamanders and fish. I didn't catch a picture of a salamander, but the
fish were easy to find and photograph. (below)
Before we went on to the second site, we took a break and had
a nice picnic in the area where we had parked.
