It is not uncommon that the spines are prepared separately and reattached, or may be partially fabricated. This would be a Ceratarges sp. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Gracias por adelantado ! Parece interesante, también me interesa saber lo que dicen los expertos en trilo. (¿Falso, restaurado? Etc, etc.). Por favor no publique precios, si desea orientación sobre su valor de mercado, envíe un mensaje privado a los expertos, en caso de que puedan ayudarlo.

Kane Posted September 21, 2021 Share Posted September 21, 2021 Bad for the specimen? Not necessarily in all cases! A lot of the excessively spiny trilobites from Morocco are exceptionally challenging to prepare, with the spines locked in very hard matrix. So, at times it is acceptable to break them off to prepare separately and reattach them later. That being said, those who prepare these without breaking the spines will produce a more premium specimen which then commands a higher value on account of labour time. Generally, the process begins by a kind of "hollowing out" of the area around the spines. Pictured here is my Comura bultyncki where it is mostly prepared, awaiting preparation of the spines. I have the option to break them for separate preparation, or to take much more time in preparing them attached. The latter will take at least 10 or more times longer to achieve. Also keep in mind that some restoration is normal and acceptable (if the seller acknowledges how much was done, and precisely where). 3 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

I commented on the private message, because it is the only way you can ask here, that kind of help. Kane, he's one of them, maybe he can guide you. 1 1 Link to comment Share on other sites More sharing options...
Kane Posted September 21, 2021 Share Posted September 21, 2021 Thanks, @Paleorunner. In this case, one of our members who prepares many of these Moroccan trilobites would prove invaluable to telling us more about this specimen with respect to any restoration, reattachment, etc. I'll tag @aeon.rocks. 2 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...

Didn't see the topic, but talked on PM with niekfermont already, so I'll just add here (as Kane said): glueing spines is not bad for the specimen, sometimes you just need to break and glue back. Btw., thanks for the nice words Kane! "Problem" of this specimen is not in restoration of the pygidium spines or the fact that spines are broken and glued back, but in a fast way... Not really a problem though, to be honest Ceratarges is not an easy bug to prep (and a well prepped one could cost you a lot of money), but here spines were removed to prep it fast (and sell cheaper), hits were blasted over and all secondary spines were lost, some tips of the spines were restored. Pretty normal prep, but not the best prepped Ceratarges and not the worst. Would be much better if spines were just prepped out and left in matrix imho. But that's just my opinion, I don't really get all this "flying prep" mania, seen to many spines break over the time after preparation.
