I know that eye protection, padded gloves for hammering to reduce harmful vibrations, and many other safety measures have been oft repeated on this forum to guard against injury, but I haven't seen much about ear protection specifically in regards to fossil hunting. First, an unnecessary backstory: I recently came to the realization that I have tinnitus and, being a bit of a hypochondriac, got myself freaked out over it. But that is, of course, silly since I can remember having tinnitus for years but just not really thinking about it. After calming down and realizing that I have had it for years, that it's very minimal tinnitus, and that it's not as bad as cancer, I have been considering ways that I can avoid making it any worse. Along with wearing earmuffs while vacuuming, I have begun to look for other strategies to avoid hearing damage. Now, some of these may be stupid questions (don't let anyone tell you, "there is no such thing as a stupid question."), but here it goes. The formation in which I hunt the most is the limestone/chalk Atco formation. One of my main means of finding fossils is just whacking on chunks of chalk, hoping to luck into some ammonites, echinoids, fish, or a perfectly articulated pterosaur clasping a new species of cretaceous mammal in its talons, and I have had much success (maybe not the last part). I mostly use an Estwing 4lb sledge and Stanely chisels with hand guards to do the job, but sometimes also use a 10 pound sledge for the harder and larger chunks. This works fine, but because I am dealing with relatively hard matrix the pinging of the sledge against the chisels can get annoying, but could it over time also cause tinnitus and hearing damage? Since I have gotten ear protection aware I have begun wearing EP3 Sonic Defenders when fossil hunting which have the great feature of allowing sounds like normal conversation and ambient noise in while reducing any noises above 85dB when the caps are off and greatly reducing all noise when the caps are in. Some of their other plugs like the EP4 and EP7 do the same thing and have more protection with the caps in, so I might get one of those too. So, my questions are: 1-When is it appropriate to wear ear protection while fossil hunting? 2-Could the pinging of my hammer against the chisel and/or chalk chunks cause hearing damage and thus tinnitus over time? 3-What kind of hearing protection do you recommend? Is what I am using ok? BONUS QUESTION-Any recommendations for padded gloves to get?

I found a fossil that looks like no other in my collection. Any help to what it would be is much appreciated. Found in a creek rock deposit in Cincinnati area. Here are several angles and lighting.

Hey, I'm just starting out and I wanted to know, what preparation tools and tactics will work best for removing limestone without damaging the specimen? (Preferably low budget) I also don't have a lot of workspace since I'm just taking a crack at this legitamate, fine-detail stuff for the first time; and after some research on air scribes, abrasives, and erasers, I realize they are much too costly and the whole air system and workbox takes up a lot of room I don't have. So is there anything you all could recommend for me?

I am looking for information on what kind of fossil this may be. It is in a limestone block wall in Ontario, Canada. There is evidence of crystallization in most of the fossils and crevices. This example is almost a foot long, 4 inches in height. There are brachiopods in many of the blocks as well, and a number of fossils similar to this example.

Our first full day of sun, sand, and surf in Jamaica bumped up against some fossils, and pseudofossils. In this area (St Ann’s Parish), more than 75% of the rock here is limestone spanning from the Cretaceous to periods in the Cenozoic. Not far from me is the Blue Mountains, the highest altitude on the island (we’re planning on a day trip to see the coffee cultivators and a 12 mile downhill bike ride). Given the abundance of limestone, it is no surprise that it features prominently in a lot of building material. Here is some fossil coral in some large, raw blocks:

Hi! I always post specimens that may be just minerals... which are the real difficult ones for me to identify. I would like to ask you what do you think about this one. It was found near the other two specimens I posted before, one of them seem to be a baryte nodule and the other one we still do not know for sure. It was found in Santorcaz, NE Madrid province, Spain, in a site where miocene fossils have been found, and where we can still find many limestones which originated in an old lake. I think this may be... only may be... part of an actinocrinites called "calyx" (?). Thank you all!

Hi everyone! What about this one? It was found in a well-known fossil site, an old cretaceous sea, in central Spain (Maranchón, Guadalajara, Spain). I would say the texture suggests a living creature of some kind. Too bad it would be a small fragment.

Nice day to all here ! Could anyone tell a tree? Location Czech Republic, limestone board. Because it has fallen in the limestone, the crust is quite cruel. It would probably break apart. Can you advise me to have a tip for conservation?

Nice day to all here. Today I have here something " UFO " for me. Localization : Czech Republic, allegedly limestone pan, Cretaceous period. It was between limestones parts. The part in red circle is really hard like carapace - not possible to cut by knife edge ( outdoor good knife ). So what it can be ?

Hi! This is another specimen I found next to the others I just posted. While the others are red and look like coral, this one looked to me as a skull at first glance. I collected it and I found out it had an intertesting soft texture over the hard stone when I started to clean it. I can say it is a bit like skin... so I stopped the cleaning process because it came off. It seems to be broken. Maybe an echinoid? The problem is always that the fossil may be really inside the matrix... Thanks!

Hello! I live in Ocala. Whenever my community starts constructing a new neighborhood, I go and search through the piles of limestone that they bring in to make the roadbed. It usually is different than the “local” softer chalkier limestone that is prevalent right here. This batch has a lot of beautiful brown and blue chert, the usual Florida fossils , some coated in druzy crystals (?) . There have been a few that I found last weekend that I cannot definitely identify. I appreciate any help, and any info on what area this limestone might be from. There are 3 photos here plus 2 more in the first reply. Thanks! Margaret

Hi, I would like to ask you if you happen to know what these fossils are. They were found in central Spain, on a farm field that I have learned to be a not well-known Miocen limestone lacustrine site. It remineded me of petrified wood when I first saw it and then I thought it could be coral. However, if you look carefully you can see that it was possibly part of a rould-like creature as I could find several pieces that actually fit. As you can see, the creature was not all the same as part of the surface where the pieces seem to assemble look totally different. The surface is not perfectly round. Please let me know if you happen to know what it is. Thank you!

T3 of Beijing international airport. All the restroom walls have limestone plates with fossil-like features. I am not sure even they are fossils or not, as some of them have the outlook----instead of cross sections----of typical fossils. If they are indeed fossils, what is a good guess of its age?

I found this fossil as a doorstop at a retirement home in Centennial Colorado. Could not believe it was a doorstop. The former owner had moved into the Alzheimer's unit and left it behind. No background on it AT ALL. Sorry about that.

Leaping Lizards, is this Fossiliferous Limestone, or am I delusional... (wait, please don't answer)

Wow... so I am learning too much stuff. This is a very dangerously addictive website. One more... a stab at an accurate id.... (ID = identification, not intentionally Freudian despite more than an occasional slip?)

Hello, I found the stone in the attached image among loose rocks on the ground on a ranch near the Chisos and Christmas Mountains between Study Butte and Terlingua, Texas near Big Bend National Park. When I found it, about 3/4 of the darker area, which appears to be some type of fossil, was exposed, which gave it the appearance of a small worm. But as a scraped it with a flat-head screwdriver, it turned out to be a closed structure with a depressed region in the center. I thought it might be a trilobite due to the shape, but having seen the trilobite fossils on this site and others, it doesn’t really look like one. The only other thing I can compare it to is a molar (tooth) about twice the length of a human’s, but smaller than s horse’s. The rock seems to be some kind of sandstone or limestone, which is consistent with formations in that area. The darker area is significantly harder than the surrounding rock. I have removed around 1/16” around and above the darker area, but figured I would consult the experts before continuing, as I’m not sure if it’s anything of interest and don’t want to waste time if it’s not, and if it is, I don’t want to damage it, as I would imagine that attacking it with a screwdriver isn’t the proper method of extraction. Any ideas and/or suggestions are greatly appreciated!
