Why the name Fossil Shell Flour®? It was important to
differentiate our product from all other diatomaceous earth
(DE) products in the marketplace. Perma-Guard DE is milled
at a consistency much like flour and is a fossilized shell
(diatom) hence the name Fossil Shell Flour®.

All diatomaceous earth is not the same. Diatomaceous Earth
(DE) packaged under the Perma-Guard Fossil Shell Flour®
label comes from an extremely pure fresh water deposit of the
diatom Melosira Preicelanica. Why is this diatom so special?
Its shell is made of amorphous silica. Its shape and
hardness are important to how it works. Its hardness keeps it
from dissolving in liquid. The holes along the diatom's wall
allow it to absorb moisture, hence its use as an anti-caking

Horse feeds contain substances such as molasses that
cause the particles to become "sticky" . Fossil Shell Flour®,
mixed in the feed, coats each particle making it difficult for the
particles to stick together. This allows the feed to "flow" better
and its absorption ability protects it from mold. No mold
means less wasted feed. By separating the particles of feed,
the animal's digestive enzymes are able to completely
surround each particle. This allows for a more complete
digestion. The animal gets more benefit from his feed and the
owner more benefit for his feed dollar.

Fossil Shell Flour® anti-caking agent is to be mixed at a rate
not to exceed 2% of the dry weight of the rations. This means,
when mixing, in every one hundred pounds of feed, 2 pounds
of feed is replaced by 2 pounds of Fossil Shell Flour® . Fossil
Shell Flour® is OMRI listed.
"After using Amorphous Diatomaceous Earth (Food Grade) in two animal feeding programs over three and a
half decades I think I am well qualified to judge wheter or not it is worthwhile, especially since it's paid us
dividends to do so. Perma-Guard Fossil Flour was the only DE used throughout this period.
Our foals are started very early on their DE regimen. We do not use any chemical worming agents or our
animals- the DE provides a natural worming program. Like our dairy operation, our horse operation stops fly
larvae from breeding in the manure. Our Kansas experience was repeated in Arizona-longer feeding- fewer
If you want your DE improvement program to work you have to feed it every day, and here's what you'll find:
Your animals general appearance will improved-they just look better. If you keep accurate feeding records you
will find you're saving money-at least 10%. Here again the answer is simple-better feed assimilation = more
money in the bank."
