Rusophycus & Cruziana from Morocco Reply to this Post Post Reply with Quote Edit/Delete Posts Report Post to a Moderator       Go to the top of this page
Dear German trilobitophyles

I've acquired recently a slab containing a cruziana and rusophycus (see image attached) clearly created by the same organism (probably trilobite but can be produced also by another arthropod).
The reseller said that this is Ordovician in age and come from Merzouga, Morocco.
I'm searching for more information about the provenance (exact age, eventual papers available, more detailed -or confirmation- info's about th elocality).
There is someone of you that can share this kind of information?

Follow the text translated in german by google (I haven't any responsability on eventual grammatical "horrors").

Ich habe vor kurzem erworbenen eine Platte mit einem cruziana und rusophycus (siehe Bild im Anhang) deutlich von den gleichen Organismus geschaffen (wahrscheinlich Trilobiten, kann aber auch durch eine andere Arthropoden) erzeugt werden. Die Händler sagte, dass dies in Ordovizium alt ist und kommen von Merzouga, Marokko. Ich bin auf der Suche nach mehr Informationen über die Herkunft (genaues Alter, eventuelle Papiere zur Verfügung, ausführlichere oder Bestätigung-Info's über den Ort). Es ist jemand von euch, dass weitere Informationen hinzufügen können?

Hi Enrico,

I don't know, what is it. But please verify, if there are stems or partials of crinoids inside. The form of the cruzianas is similar to a form of a crinoid stem. Sorry, if am totaly wrong... :rolleyes:

I'm sure that this is a Cruziana (tracks of the podomeres of trilobites leaved in the sediments) and Rusophycus, show in the upper left side of the slab corresponding at the resting place of the arthropod.
I've attached another specimen coming from the same site (Ordovician of Morocco) show in my book.

You don't be sorry, all people is here to understand and learn from everyone :D

Dear Enrico

Here a scheme of trilobite traces. It is obious that the same animal can produce very different traces depending on the speed.

You will find some literature on google searching for "arthropod trackways".

More information you will find in the excellent homepage of Sam.

http://www.trilobites.info/trace.htm

Best regards

Louis

Dear Louis

thank you to post this page and for your private message.

This page come from the Seilacher's book "Trace Fossil Analysis" published in 2007 by Elsevier.

I've acquired this book last year and I suggest, for who is interested in "ichnology", to spent a little amount of money to acquire this very interesting book.

Clearly it is not dedicated only to trilobites tracks , but it cover all the periods, from Precambrian just today.
It is very well illustrated with didactic drawings and pictures.

To have a look at this book follow this link:
