Conodonts an important and enigmatic group of vertebrate
microfossils known from the late Cambrian until the Triassic (when
they became extinct). The conodont animal itself is rarely preserved
as it had no hard parts, instead it is the intricate jaw elements that can
be found in abundance. The animal was a small, eel-like vertebrate
with large eyes and they were once abundant in the oceans. The
closest extant animal is the lamprey, which has a jaw structure similar
to those of condonts, although the two are not closely related.
The jaw elements can only be collected by dissolving shales and
limestones in acid, but can be beautifully preserved. A vast array of
forms are known and they are fascinating to view and study under the
microscope. Each species of conodont had numerous jaw elements
(almost two dozen in some species) which could be wildly different in
Early researchers assigned each jaw element to a different species,
but it was only with the discovery of complete animals that it was
confirmed multiple jaw element forms occurred in a single species.
The image left shows a reconstruction of Lochrea. All of these jaw
elements were from a single species, but in the older literature each
was classed in a different genus, which at times does confuse things.
Mississippian Lochriea conodont jaw assemblage - £25/$40
From the Chappel Limestone (Lower Mississippian) of Texas this is a rare
composite jaw assemblage of the genus Lochriea. It has been established
that these four types of condont made up the jaw apparatus of this genus.
Each collection shows the nature of the four elements and includes both
blade and platform types. Rare. Comes housed in a micropalaeontology
slide. Each specimen measures approximately 1 to 2 mm.
The following conodont collections are consist of identified specimens housed in custom
labelled capsules. Most specimens are complete and ideally suited for study, photography and
Harding Sandstone Conodont, shark and fish collection - 26 species - £50/$75.
Middle Ordovician of Colorado. This is an excellent collection as it includes some of the earliest
vertebrates including fish and shark scales and a diverse conodont fauna. Last one
Chappel Limestone Conodont collection - 30 species - £60/$90
From the lower Mississippian of Texas. This is the best conodont fauna we have ever come
across as the preservation is excellent and the fauna extremely diverse. Highly recommended.
The identification card shown right illustrates the preservation that is typical of the Chappel
limestone. Many of the forms shown on the ID card are included.
Prospect Hill Formation Conodont collection - 12 species - £25/$40
From the lower Mississippian of Iowa. This is another nice fauna typical of the
period. Very good preservation. The identification card (right) shows the typical
preservation and condont forms in the collection.
The Mississippian faunas are a nice contrast to the earlier Ordovician and
Conodont rich matrix
The following matrix samples contain abundant conodonts. Generally preservation is very good
and many conodonts can be found, especially the more common forms. This material is great
for classroom use or study. It is also suitable for anyone wanting to put together their own
conodont collections, although the number of species that can be obtained is less than in the
collections offered above. Still, this is excellent and rare material. Additional images for all of
these samples can be found on our Vertebrate Microfossils page.
