Jack Kallmeyer replied to the topic Mosasaur Jaw? in the forum What Is It? 2 days, 3 hours ago
2 days, 3 hours ago2 days, 3 hours agoOne of the many Moroccan fakes. The teeth are real mosasaur mated to a faked jaw. Note the sketchy unrealistic material between the brown part of the tooth (the real part) and the jaw. It is possible that they mated the real teeth with a real piece of some kind of jaw bone but these teeth were never in that jaw. You didn’t say what you paid b…[Read more]

4 years, 2 months ago4 years, 2 months ago@samantha-ocon , @sadie-mills I have an answer for you. I got the following information from one of the prep lab people who actually use these tools:
The normal tool we use is Chicago Pneumatic scribe which comes in any number of sizes depending on what you want to use it for. Paleo Tools has a wide selection of the Chicago and also se…[Read more]

4 years, 2 months ago4 years, 2 months ago@samantha-ocon I could check to see what they use in the Cincinnati Museum prep labs. Maybe that will help. I am laid up with a foot injury so I’ll have to get one of my friends to check.

4 years, 2 months ago4 years, 2 months ago@samantha-ocon I am sorry I can’t offer any help along those lines. I don’t use this type of equipment as it isn’t generally needed for most fossils around here. “hard core” people who do lots of this type of work are the ones who use these. If you do get one of these remember that you still need a strong suction device pulling away the mat…[Read more]

Don’t ignore his advice on the dust. Safety glasses as well. Cheap air scribes are available, but the metal used in the tip may not have the best metallurgy.

@david-coxiii, @samantha-ocon I know of a mineral collector who did some lapidary work and had used a wet diamond saw. He breathed the water spray that comes off the saw over many years. This spray contains fine rock dust. He now has a serious lung disease.

4 years, 7 months ago4 years, 7 months ago@sadie-mills@carl-lewis A lot depends on the preservation material for the trilobite. Most will be calcitic and will be adversely affected by any chemical cleaner that will dissolve limestone. To remove loose or soft shale or mud a toothbrush with water and an optional mild detergent will help. If the limestone matrix is covering part of t…[Read more]
