<div>Epoxy should work well, especially with small to medium Paleozoic invertebrates. A good mold/cast maker could do a very good job of pigmenting and "nature-faking" with the resin itself so that there is nothing to wear off the surface. You could also
use low-melting-point metals in high-temp silicone, but that's probably more than you need. Feel free to contact me off-list if you need details.</div>

At the State Fairgrounds we recently installed an Ohio geologic walk through time (see <strong style="FONT-SIZE: 0.98em; COLOR: rgb(74,0,21); LINE-HEIGHT: 15px; FONT-FAMILY: 'Trebuchet MS',Arial,Helvetica,Verdana,sans-serif; WHITE-SPACE: nowrap; BACKGROUND-COLOR: rgb(251,251,239)"><a style="FONT-SIZE: 0.98em; COLOR: rgb(74,0,21); LINE-HEIGHT: 15px; FONT-FAMILY: 'Trebuchet MS',Arial,Helvetica,Verdana,sans-serif; WHITE-SPACE: nowrap; BACKGROUND-COLOR: rgb(251,251,239)" href="http://geosurvey.ohiodnr.gov/" target="_blank">http://geosurvey.ohiodnr.gov</a>) </strong><span style="FONT-SIZE: 10pt">with
large boulders from each of the Paleozoic periods represented by our bedrock. The walk is to scale, with each foot representing one million years although we condensed the Precambrian (since it is entirely buried in this state) and the Mesozoic-Cenozoic (since
we have no bedrock from those times).</span></div>

<div>We would like to add casts of representative fossils. What can we use that would be strong enough to last a few years in our weather (it was 8 degrees out there yesterday!) and being touched by thousands of fingers.</div>
