What An Unprepared Spiny Trilobite Looks Like
Posted: 03/05/14 02:23 PM : By Matt Heaton

I've seen many questions about how the spiny trilobites from Morocco such as a WalliseropsComura, or Koneprusia can be preserved with free standing spines after nearly 400 million years.  

The answer is when they are found they are encased in solid limestone, and are found by literally sledgehammering blocks of limestone looking for cross sections of trilobites.  The pieces are then glued back together and the surrounding matrix (rock) is removed using air abrasive techniques (think minature sand blaster) under high magnification.  A well prepared trilobite of one of this species often takes in excess of 40 hours of work by a master preparitor.  Not a task for the impatient person but the results can be spectacular.  This is also the reason for the price on many of these trilobites, it's the preparation cost, more than the cost of the actual fossil you are paying for.

Here's an example of a spiny Walliserops trilobite in it's unprepared state.  This is the one with long trident coming off of it's head and about 40 free standing spines.  This particular specimen I'm planning to prepare sometime in the next month and will post a time lapse of the preparation process when I am done.


How To Secure A Spiny Trilobite For Transport
Posted: 03/04/14 02:36 PM : By Matt Heaton


Shipping and transporting trilobites and other fossils with delicate free standing spines is a real challenge.  One of the most effective methods is to physically bolt the fossil to the inside of a container so that nothing but air is touching it during shipping.  This is how most of the spiny Moroccan trilobites gets shipped to me from my supplier.  

I've had some questions on how this is actually accomplished so after some experimenting here's some instructions.

The Story Behind Starting FossilEra
Posted: 02/22/14 07:11 PM : By Matt Heaton

Recently I have done a number of interviews related to FossilEra and first question that always comes up, is what led me to start the company.  

Like many kids I grew up being obsessed with dinosaurs and fossils.  My parents can tell stories about how I would spend all day digging in the sandbox looking for dinosaurs.  I’m sure I checked out every book at the library related to fossils a dozen times, and I dreamt of being a paleontologist when I grew up.

A Tale Of Two Comura - Reconstructed Trilobite Spines
Posted: 02/17/14 05:04 PM : By Matt Heaton

Unfortunately, there is a long history of fake and heavily restored fossils being marketed as authentic.  Even a lot of well known dealers don't disclose the amount of restoration work that has been done on specimens they sell.  In many cases I don't think it's a problem of dishonesty.  I think most simply don't know better.  The methods of restoring/reconstructing fossils have continued to advance and many of the signs people are used to looking for just don't work anymore.

I go through great lengths to ensure that the fossils being sold on FossilEra are accuretely represented.  I am able to fall back on nearly two decades of experience collecting and preparing fossil trilobites to assist in this.  For example some of the reconstruction on trilobites  has reached a level that even with my experience, and under microscope I sometimes can't pick it out.  That's why I often need to resort "destructive" methods to expose potential restoration such as air abrading away possible paint or using solvents.



Here is an of the very spiny trilobite, Comura bultyncki which has a full compliment of over 40 vertical spines along it's back.

Show And Tell - Double Walliserops Trilobite Plate
Posted: 02/07/14 10:08 AM : By Matt Heaton

This is a specimen I picked up for my own collection at the Tucson mineral and fossil show last week which I thought I'd share.  It's the most impressive and best prepared plate of the very weird trilobite Walliserops trifurcatus which I've ever seen.  It comes from the Devonian aged rocks near Foum Zguid Morocco and was prepared by one of it not the best preparitors of Moroccan trilobites, Hammi.

New Trilobite Arrivals From Morocco
Posted: 01/19/14 01:39 PM : By Matt Heaton

I was very excited to have a big box of trilobites arrive from Morocco yesterday.  It taken over a month to reach me, so I had been getting pretty impatient.  There are lots of more common species as well as a few nice spiny ones protected in plastic cases.  The quality of trilobite preparation available from Morocco has come a long way since I first started collecting trilobites 15 years years ago.

There is still plenty of work to do before they get listed on FossilEra.  I'll go through every one of them to verify there is no major restoration work and that I can accurately detail any minor restoration in the descriptions.  Some types of restoration with reveal itself under black light, while much of it will require close examination under high magnification looking for incorrect textures or colors.  

Top 10 Paleontology News Stories Of 2013

Intact Skull of Homo erectus Shakes the Family Tree

In Dmansi, Georgia, a 1.8 million year old skull is found in the same area of collapsed carnivore dens as other H. erectus from the early Pleistocene. This particular skull is strikingly complete, and belonged to an ancient human who was eaten by one of several large carnivores that also shared the local watering hole. 

What makes this discovery so astounding is that the unusual dimensions of the skull, along with those of other local skulls, reveal that there was a wide breadth of normal variation in Homo erectus.  This suggests that several described human ancestors from Africa may not be separate species, but may be variants of H. erectus.  This is a ground breaking idea regarding our ancestors that radiated from Africa, and who may have been the first of our lineage to use fire to cook food.  Critics suggest that while this new discovery is an amazing new reference for species diversity, caution must be used before entire branches of the human family tree are summarily chopped off.  More skulls from Asia are needed to corroborate observations.

Ancestral Spiders of the Cambrian Reveal Their Nervous System

A new fossil relative of spiders and scorpions was discovered in China- and this weird creature of the Cambrian marine is stranger than fiction.  A member of the Alalcomenaeus genus, this megacheiran (“great-appendage”) arthropod  lived 520 mya, among the ancestors of crustaceans.  This new species is believed to have been 1 inch long, possess two pairs of eyes, had an elongated and segmented body with 12 pairs of appendages, and had a pair of scissor-like head claws. 

The organization of its neural anatomy reveals a similarity to the chelicerata (horseshoe crabs and scorpions).  In fact, the brain is like that of modern spiders.  Scientists are currently searching for a shared ancestor between this new creature and the ancient crustaceans.
