Wax paper
From Wikipedia, the free encyclopedia
Wax paper (also called waxed paper) is a kind of paper that is made moisture proof through the application of wax.
The practice of oiling parchment or paper in order to make it semi-translucent or moisture-proof goes back at least to medieval times. Thomas Edison claimed to have invented wax paper in 1872[citation needed] , but what he really invented was a cheap and efficient means to manufacture such paper.[1]
Wax paper is commonly used in cooking, for its non-stick properties, and wrapping food for storage, such as cookies, as it keeps water out or in. It is also used in arts and crafts.

So that answers my question. I guess it can be either way, and that's the same brand I use (see picture).
I also didn't collect 5 rocks. I have many rocks I've collected over the years, as well as shells from the beach. I have a small snail shell obsession, and have one or two dishes for the tiny ones, and have a few window sills filled with the larger Moon Snail shells. I'm very intrigued by those; they seem very female to me, like little perfect breasts. Except that they all face the same direction. Also from Wikipedia:

Naticidae, the moon snails or naticoids, is
a family of small to medium and large-sized predatory sea snails,marine gastropod molluscs in the clade Littorinimorpha.
It has been estimated that worldwide there are about 260–300 Recent species in this family, which is assumed to
have originated in the late Triassic or in the early Jurassic. Members of the Naticidae can easily be
recognized by their shell shape, distinctive markings and peculiar predatory behavior.
Distribution
Members of this family are found in all seas, from the intertidal zone to a considerable depth. The greatest species and
generic diversity is found in tropical regions, but Naticidae are also abundant in
moderately temperate as well as Arctic and Antarctic waters.
[edit]Habitat
Moon snails live on
sandy substrates. They are often found ploughing along in the sand searching for prey.
[edit]Shell description
The shells of naticids
are turbinate to globose, usually solid and smooth,
the aperture without either siphonal canal or sinus, and the inner lip parietal callus is often reflected across the umbilicus, joining a spiral funicle from within. The operculum is tight fitting, either horny or calcareous depending on the genus.
[edit]Life habits
Naticids are very active carnivores.
They feed largely upon bivalves, but will attack almost any shelled mollusk they encounter in the sand, such as scaphopods and gastropods, including other moonsnails. They envelop the prey and then bore a hole into the shell with the aid of their radula and
an acid secretion, after which theproboscis is inserted through the round hole. The very neatly drilled round hole, which has a "countersunk" appearance with chamfered edges, is a characteristic diagnostic sign of moon snail predation.
In the breeding season, the female moonsnail constructs an interesting interrupted ring-shaped nidus of agglutinated sand grains, lining the inside with thousands of small
eggs. These objects wash up fairly often, and are known by
the common name "sand collars" because of their resemblance to an old-
fashioned removable shirt collar or false-collar.
[edit]Classification
Most authors suggested a distinct separation of the Naticidae into four subfamilies: Ampullospirinae, Naticinae, Polinicinaeand Sininae. This arrangement is mainly based on morphological
data, such as the surface material (calcareous in the Naticinae,
corneous in the Polinicinae and Sininae) and size of the operculum or the morphology of the shell.
The new taxonomy of Bouchet & Rocroi (2005) however
only recognizes three subfamilies :
- Globisininae Powell, 1933
- Naticinae Guilding, 1834
- Sininae Woodring, 1928
The subfamily Polinicinae Gray, 1847 is an older synonym of Naticinae
To date, the naticid species are assigned into the following genera:
- Amauropsis Mörch, 1857
- Bulbus Brown, 1839
- Calinaticina J. Q. Burch and Campbell, 1963
- Cryptonatica Dall, 1892
- Eunaticina Fischer, 1885
- Euspira Agassiz in Sowerby, 1838
- Falsilunatia Powell, 1951
- Friginatica Hedley, 1916
- Globisinum Marwick, 1924
- Gyrodes Conrad, 1860
- Haliotinella Souverbie, 1875
- Lunatia Gray, 1847
- Natica Scopoli, 1777
- Naticarius Duméril, 1806
- Neverita Risso, 1826
- Polinices Montfort, 1810
- Proxiuber Powell, 1933
- Sigatica Meyer and Aldrich, 1886
- Sinum Röding, 1798
- Stigmaulax Mörch, 1852
- Tanea Marwick, 1931
- Tectonatica Sacco, 1890
- Uberella Finlay, 1928
