This is a very nice and very unique fossilized Ammonite from
Madagascar. The exterior has been ground smooth, polished
to show the suture lines, and the interior shaped into a
functional bowl. The Ammonite has pretty brown and tan
exterior colors with the highly detailed tan suture lines.
The inside of the Ammonite shows the yellow calcite in the
different chambers in the center. The lovely specimen
measures almost 5 5/8" x 4 1/2" x 1 3/8" thick and weighs over 1 pounds. Very nice!!

Belemnites
or Belemnoids are an extinct group of marine Cephalopod which are very similar
to the modern Squid and closely related to the modern Cuttlefish. The
possess an ink sac, but unlike the Squid, they have ten arms of equal length
and no tentacles.

Ammonites are extinct members of the cephalopod group of mollusks.
Only a limited number of species have survived to the present day which
includes the squid and the chambered nautilus. Ammonites had a multi-chambered
shell, and added more chambers as it grew, always living in the outer
chamber. They lived in the Cretaceous period some 63 to 130
million years ago.

These Moroccan
fossils are among the oldest cephalopods. They were abundant during
the Paleozoic era some 350 MM years ago and now make up the Atlas Mountain
range of central Morocco. There were two Nautiloid forms present in
the Moroccan Devonian sea. The Goniatites is an extinct
relative of the Ammonites, it possessed an external shell, which
is has a spiral form with internal chambers. The
Orthoceras was straight shelled cephalopod with the internal
chambers. They were related to the modern day
chambered nautilus and the squid.

Orthoceras is a genus of extinct Nautiloid Cephalopod. These fossils
are common and have a global distribution which occur in any marine rock,
especially Limestone. These are slender, elongated shells with the middle
of the body chamber transversely constricted and a sub-central
orthochoanitic siphuncle. The surface is ornamented by a network of fine
lirae or fine lines/ridges. |

Trilobites are hard-shelled, segmented members of
Arthropoda and the class Trilobita that existed throughout
almost all of the Paleozoic era, flourishing in the earlier part
of it and slowly declining in the later part. The most common
trilobites were about 2-7 cm (1-3.5 in) in length, but over
their long history they ranged in size from 1 mm-72 cm (.04
in-28 in) and exhibited so much variation that they are
classified into nine (or possibly ten) orders with more than
15,000 species. The smallest species are presumed to have been
part of the free floating plankton, while the more common,
mid-sized species probably walked along the sea floor filtering
mud to obtain food, and the larger varieties may have been
swimming predators.

This fossilized Lobster is from Gunn Point in Darwin Northern Territory,
Australia. It was formed after the area was catastrophically buried by
an intense cyclone, with Mangrove trees in Calcium rich mud. This particular
specimen, although not complete is well preserved and measures 4" x 2"
x 1 3/4". It would make a great addition to any fossil collection.

Here is something different from the Rock Shed's fossil department.
This is a very well preserved, above average quality
Crinoid specimen. The Crinoid
has several very detailed calyx (flowery head) with pieces of their
stems attached. It measures approximately 12 1/2" x over 10" wide
x nearly 3/8" thick, weighs almost 8 pounds and has not been polished.
Since this was once part of an ancient sea floor other fossils can be
seen from when the specimen was cut and prepared for display. Very
nice!

Crinoids, also known as sea lilies or
feather stars, are marine animals that belong to a class of Echinoderms.
They lived in both shallow and deep water. They are characterized
by a mouth on the top surface that is surrounded by feeding arms.
Crinoids usually have a stem used to attach themselves to a substrate, but
many live attached only as juveniles and become free-swimming as adults.
There are only a few hundred known modern forms, but crinoids were much
more numerous both in species and numbers in the past. Some thick Limestone
beds dating to the mid- to late-Paleozoic are entirely made up of disarticulated
crinoid fragments.

Sand Shark or Otodus obliquus – (the Great Grandfather of the
Megalodon) is one of the earliest mackerel sharks. These teeth are
noted for their wide triangular crown and large side cusps
(occasionally multiple side cusps). The Otodus obliquus was the king
of the early Eocene, approximately 50-55 million years ago. These
large teeth are very showy, making them a must have for every fossil
shark teeth collection. Large Otodus obliquus teeth are not easily
located in the phosphate pits in Atlas Mountains of Morocco, but can
still be affordable.

This tooth is from the largest shark ever known to live. The
Carcharocles Megalodon sometimes ranged in size up to 60' in length and
weighed over 52 tons. This huge monster is the largest predatory
fish that ever lived, second only in size to the sperm whale. Fossil
teeth have been found that exceed 7 inches in length. These sharks
lived in the Miocene period some 23 million years ago to the Mid Pliocene
times, 3.6 million years ago. This specimen is from South Carolina.
