About triops.

 

Triops are comparatively common fauna in rice paddy field of western part of JAPAN.

So easy observation sets are sold in AMAZON Japan.

Amazing design! I am actually making a trilobite model out of a Styrofoam cast and several plaster mixtures. I don't think mine was going to be as detailed and accurate though!    :trilowalk:     :trilo:      :trilosurprise:

I am a new member, this is the first time I have seen you work, very nice!  I have been to a few art shows, some of the other artists use a product called Zbrush.  I am willing to try using it but I am afraid the learning curve might make it slow and clumsy, at least at first.  I normally work in clay then make a silicone rubber mold of the sculpture so I can offer limited editions then go to a foundry to have it cast in bronze.  I am working on a heteromorphic ammonite piece now but am still trying to find out the spine number for the genus I want to sculpt.  

My fist paleo themed piece was a sculpture of Isotelus maximus, I sculpted the trilobite and placed it on a bronze base cast from a piece of fossiliferous limestone I collected behind the house.  The limestone already had crinoids, bryozoans and brachiopods in it, I added some castings of the trilobite Flexicalymene meeki.

Bronze is a cool medium to work in, it will support a lot of the detail and small fine features like the appendages, it is very strong to cantilever the sculpture out to show movement and will last for ...?  A long time.  If you choose to cast you work bronze does offer a lot of advantages, price is a problem however.  I was charges $720 to cast the sculpture, I have cast several in this edition and this price is relatively reasonable.

I have not been here for a while, sorry

 

@ comsuella2293

Very beautiful model. It does not seem to have a UV map. If so, you should consider to create one to paint a more complex texture. Blender has the ability to create UV map.

 

@ james herrmann

Your sculpture is impressive and original, what is its size?

 

I continue my work on Trilobites with the ontogeny and the life history . Here is a reconstruction of a pelagic protaspis of Isotelus. The benthic exemple (Physemataspis) is in preparation.
I update my website with the study of "La face cachée du Trilobite" (The hidden face of the Trilobite).

Sorry but the website is in French, automatic translation seems not to be so bad.

A benthic protaspis, the exemple of Encrinuroides.

The ontogeny and life history are terminated and now I am working on locomotor activity. This is a very difficult part of working on Trilobites. Not easy to understand how millipeds move in order to inspire them to animate a Trilobite

Love the quality of Your reproductions!

 

I would think a horseshoe crab or a lobster would be a closer match (for locomotion) than a millipede. (Just a thought.)

Darwin said: " Man sprang from monkeys."

Will Rogers said: " Some of them didn't spring far enough."

A lobster it is 5 pairs of locomotory appendages, Isopoda 7 pairs, horseshoe crab 5 pairs.

A Trilobite (Triarthrus) 17 pairs, thus a Centiped like Glomeris is a good extant equivalent.

Yes doushantuo the reading of Sidnie Manton's papers are my main source of information. This lady did an extraordinary job with very simple material.

Now, I understood how centipedes walk and reproduice it with my 3D software.

An example (choose a loop reading)

Very good job Comsuella, but your Isoletus is a bad boy. What does he drunk?:)

 

My last update in French but the movie does not need to understand French it is a silent one

I do not speak French, but that video was very informative. Well done!

Hi,

 

Would not I already have seen that this morning on a French forum? The video is very instructive !
