A Quick Trip to Deer Lake Nan and I spent half a day at Deer Lake which is still beautifully exposed by the highway construction with lots of rock facings, rubble piles and exposed walls, also large rocks and boulders. There is a lot of iron content in the shale below the "Tully limestone" strata which is near the top and just below the limestone there are Dipleura trilobites although we have found mostly body parts and segments. I also noticed that a lot of the assemblages include shells and other creatures were already dead when they were fossilized. Many of the shells in large assemblages are different types of brachiopods/pelecypods with holes in the shells suggesting they died and accumulated like shells do today at ocean shorelines, then were fossilized. Some clusters where all or most of the species are the same with no deterioration or predation suggest that they died together at the same time. Students and fossil hounds have been scouring this area but there is a lot more to find and more being revealed as the construction continues. Nan and I have had pretty good luck this year with construction sites - most notably of course the Wattieza tree stumps we discovered. We do have some questions about some of our Deer Lake finds - comments welcome: 1. Trilobites We only found 2 trilobites this trip - this one is curled under at the bottom which is shown in these views: 2. Crinoids These are some interesting crinoids: 3. Pleurodictyum Coral Patterns - (Not Clam Mold Patterns) I thought these strange patterns were in the mold of a clam - there are tons of clam fossils at Deer Lake, some fairly large. These patterns were in a mold but apparently this is from a coral. 4. Spaghetti Shaped Fossils And finally - here are some "spaghetti strands" Nan was wondering about - not sure what these are: We found a LOT more fossils, including some assemblages that will make some nice displays. We were looking for larger pieces for display and found one large shell covered rock that is almost 2 feet long.
