HOW TO HELP US :

We greatly appreciate receiving off-prints from researchers as these papers are helpfull for us. Off-print donation is the better manner to help us in scientific dissemination if you're a researcher. About recent or fossil echinoids, published recently or already aged, all paper related to echinoderms (principally echinoids) are helpfull. If you want to do so, please send them to us through email or snailmail (just ask our postal references by email : in this case we will participate to postal expenses, if needed). Thanks by anticipation for your contribution. In the other hand we can help you by sending you scans from very ancient litterature, if some figurations are lacking in the library with which one you're working (only if there is no copyright or  if this one has expired)

07/08/2011 This time, we do not propose to see new galleries of sea urchins, but an article. For a long time it had not happened, but we lack of contributors (by the way, if you are interested in publishing texts do not hesitate!). For what we are interested in the ad, it will be a paper about the great echinologist Gustave Cotteau. Following his death, two of his contemporaries have published obituaries. In them is told the life of our beloved paleontologist. His life, as well as science of man every day. These obituaries are transcriptions of articles in scientific journals. We hope that through these articles you will learn more about him, the one that everyone here know the name. We added an engraving of a portrait of him, this type of representation is quite rare.
 
15/05/2011 As usually, this message to inform you about another big update. I promise that in the next one, an article will be proposed ! But... this is a surprise for you. For the moment, let's enjoy this major publication. You'll notice that a big part of it is devoted to Stomechinids, and especially to the genus Thierychinus with a lot of big and gorgeous specimens.

03/11/2010 As usually, I'm late, so late... but it was essentially for a good reason : this update is one of the biggest I ever uploaded on echinologia. So my apologies for this long time without news. Maybe you've noticed also, that diagnoses and descriptions are updated also at the same time I publish new specimens. The hardest one was without contest, the one dedicated to Hemiasteridae family, as it is so extensive. lol

28/03/2010 There has been no updates since a few weeks, as you noticed ! As on February the work focused on a more important contribution than only pictures. The following families, (and also all genera and species figured) that follow are now accompanied with the original diagnosis or descriptions of contemporary writers.
Please, note that they are verbatims, or extracts of original works when pointed out. We hope that this work will be helpfull for you and feel free to write us if you've more precise informations than those reported in these pages.

24/02/2010 There has been no updates since a few weeks, as you surely noticed ! The work focused on a more important contribution than only pictures. Indeed, families, genera and species that follow are now accompanied with the original diagnosis or descriptions of contemporary writers. Please, note that they are verbatims, or extracts of original works when pointed out. We hope that this work will be helpfull for you and feel free to write us if you've more precise informations than those reported in these pages. The latest updates are for the following families : Acropeltidae, Acrosalniidae, Aeropsidea, Anorthopygidae, Apatopygidae, Arachnoididae, Arbaciidae, Archaeocidaridae, Archiaciidae, Astriclypeidae, "basal meridosternata", Brissidae, Brissopsidae, Cardiasteridae, Cassidulidae, Catopygidae, Cidaridae, Clypeasteridae.

14/12/2009 I'm late with the "sunday gallery" : I've little problem with my health... It has also taken a time for this update, because there was a lot of text to add (a lot of pics also). HOLASTERIDAE :   Cibaster leymeriei (Cotteau,1887) ; Cibaster minor (COTTEAU,1860) ; ARBACIIDAE : Gymnodiadema choffati DE LORIOL, 1884 (four big specimens) ; Codiopsis lorini COTTEAU,1851 (three perfect specimens)

06/12/2009 Today, we added some new specimens in the Cassidulidae family :  Cassidulus trojanus COOKE,1942 ;  Eurhodia amygdala (DESOR,1863). And as you'll see, I added also a large verbatim of orignal/subsequent descriptions for the whole family. Hope it will helps. I'll be glad to receive your comments about this new feature.

22/11/2009 Rainy week end, I can upload ! I hope that ancient diagnoses, descriptions are usefull for you. For instance, ECHINARACHNIIDAE :  Astrodapsis davisi GRANT & EATON,1941 ; Astrodapsis whitneyi REMOND, 1864

22/11/2009 Nucleolitidae : /Asterobrissus fourteaui/ (LAMBERT,1913) : As you certainly noticed, this link is not correct. The real echinoid to be showed wasn't at all a Nucleolitid, but Aphelaster integerer, a toxasterid. My apologies for this inversion.

22/11/2009 Today, we added some new specimens and also new taxinomic descriptions, for : Acropeltidae : Acropeltis atlantica REY,1989 ; Archiaciidae: Archiacia santonensis (d'ARCHIAC,1855) ; Nucleolitidae : Asterobrissus fourteaui (LAMBERT,1913)

14/11/2009 I start again to upload new galleries. It has taken a time, because there was a lot of photos to shoot. IMPORTANT : I added since today the original description, diagnosis for genus and species. Let me know by email if this is useful or not for you. ORTHOPSIDAE A big species represented on the site by five specimens : Orthopsis ovata (COQUAND,1862) ; PHYMOSOMATIDAE : big Thylechinus also Thylechinus schlumbergeri (COTTEAU,1864).

18/07/2009 As you has certainly noticed, the index pages called "galeries" was too long to be on a single screen and you have had to use the scrolling. So I decided to split it in "letter by letter index", it's more difficult for me to manage but give you the possibility of a smoother surf. Don't hesitate to give me your appreciation about this modification. For the instant, just a single update regarding : Brissidae : Metalia gneffensis (FOURTEAU) ; Micrasteridae : Micraster coranguinum (LESKE) ; Toxasteridae : Macraster pseudoelegans ADKINS ; Oligopygidae : Oligopygus haldemani (CONRAD) ; Orthopsidae : Orthopsis miliaris d'ARCHIAC ; Toxopneustidae : Schizechinus serialis (POMEL) ; Galeropygidae : Galeropygus agariciformis (WRIGHT) ; Hemiasteridae : Leymeriaster similis (d'ORBIGNY) ; Basal meridosternata (Holasteridae ?) : Crassiholaster subglobosus (LESKE)

24/06/2009 : After the bad last week during wich my hosting compagny had failed to assume his responsability in terms of technology, nor in communication... The site was down as you've noticed, without possibility to upload something, Raid disks down also... As I would like to stay as polite as possible, I will not give my sentiment about this situation, nor about this company, just it's name : online.net

for what we're occupying, I continue to inform you about the news related to the galleries. Today, we publish :
Clypeolampas leskei (GOLDFUSS) Clypeolampadidae ; Hemiaster corculum (LAUBE) Hemiasteridae ; Hemiaster withei (CLARK) Hemiasteridae ; Encope emarginata (LESKE) Mellitidae (juvenile specimen)

MICRASTERIDAE   Cyclaster archeri (TENISON & WOODS) ; HEMIASTERIDAE (Palaeostominae) Ditremaster covazi (TARAMELLI) ; Bolbaster planedeclivis (GREGORY) ; TOXASTERIDAE : Epiaster crassissimus (DEFRANCE) ; ANORTHOPYGIDAE :   Anorthopygus orbicularis (GRATELOUP)

01/06/2009 Last update for today : lets have some polish echinoids. Pygasteridae : Pygaster morrisi WRIGHT, two bid specimens (not yet cleaned... because of the concrete hard limestone) ; Pygaster tenuis AGASSIZ.

01/06/2009 Twice a day... This afternoon was dedicated to : SCHIZASTERIDAE : Periaster elatus (DESMOULINS) ; Periaster verneuilli (DESOR) ;
PRENASTERIDAE :
Anisaster mossomi (COOKE) ; HEMIASTERIDAE : Hemiaster angustipneustes DESOR ; Mecaster amaliae (PERON & GAUTHIER) ; MICRASTERIDAE : Micraster leskei DESMOULINS.

01/06/2009 Just a word about the previous message. I wrote that all specimens figured in the last update were common... But as a matter of fact, I have to correct with this : "except" Pedinopsis, wich is as scarce as possible, as you know certainly. Today I would like to show another specimens of Pseudogibbaster tercensis (5 new) : they are very different in their global shape and also in the ambulacrum design.
Two of them have closed ambulacra in the proximal area (apex zone) and a impair ambulacrum shorter than normally. Maybe they are females ? If someone have an idea about this, I will be glad to read something about this. The other figurations are about : SCHIZASTERIDAE :
Linthia canaliculata (COTTEAU) ; Linthia wilmingtonensis CLARK ; MICRASTERIDAE : Ovulaster gauthieri  COTTEAU ; TOXASTERIDAE : Pliotoxaster paquieri LAMBERT ; HEMIASTERIDAE : Hemiaster stella (MORTON) ; Mecaster meghilensis LAMBERT

29/03/2009 Today you will see some pictures related to the toxasteridae. Maybe should I use the term "toxasterids" or even "spatangoids", since the classification is always under work and so unclear. But you understand what I mean, no ? If somebody has an idea about...
On the other hand, please let me know if some of the new pages we have published recently contain broken links or other errors. Many thanks.
I'm sorry to say that from today the pictures will be bigger (around 100-110 kb) and therefore longer to load for those who don't have fast internet connection. But on the other hand, the quality is better, because of the low compression ratio.

28/03/2009 No galleries since at least three week : my apologies for this, but I was (very) busy. I'm proud to present the following of the big collection of Hemiasterids.
In addition you'll get one representant of Aeropsidae and another one of Holasteridae, just click below please. Holaster senonensis ; Homoeaster auberti ; Leymeriaster similis ; Mecaster pseudofourneli (two specimens, the second one has a special peristome) ; Mecaster scutiger ; Mecaster syriacus.

21/02/2009 This time, at least 90 % of the update is dedicated to Hemiasteridae, one of the most common, most variable genus. A morphological plasticity just for collector's pleaure.
But I cannot resist also to put one or two cidarids, one or two Micrasters...

15/02/2009 Sunday, sunday... sunny sunday... COLD sunday. Outside temperature is below 5°C and I'm happy to be behind my desk, preparing new galleries for you all. Today I would like to illustrate the variety of echinids through nine species as different as possible. Just take a look ! Acrocidaris nobilis AGASSIZ, Conoclypus vilanovae (COTTEAU), Eurhodia rugosa (RAVENEL), Eurhodia rugosa depressa (RAVENEL), Gitolampas desmoulinsis (DELBOS) 75mm new specimen better than the first one, Gitolampas scutella (LAMARCK), Heliophora orbicularis (LINNE) var. dentata LESKE, Heliophora orbiculus var orbiculus (LINNE) very scarce in this condition, Rotuloidea fimbriata ETHERIDGE.

08/02/2009 for the end of this week, I decided that il would be better for me to shoot some pictures of echinoids than having my nose in ancient litterature. That's why you will get only this update with some common echinoids. Be sure that determinations for Collyrites can be discussed, because there's nothing clear for this genus... Collyrites elliptica (LAMARCK) ; Collyrites dorsalis (AGASSIZ) ; Collyrites cheveti VADET et al. ; Cardiopelta bicordata (LESKE) ; Dendraster gibbsi (REMOND) ; Dendraster venturaensis (KEW).

You can enjoy the pictures of these specimens here (holotype and one of the paratypes) : Rhynchopygus janchrisorum Holmes, Ah Yee & Krause, 2004

I've also updated the family Saleniidae with the followings : Leptosalenia prestensis (Desor,1856) ; Leptosalenia grasi (Cotteau,1861) ; Leptosalenia mexicana (Schlüter,1887) ; Leptosalenia texana (Credner,1875) ; Salenia (Salenia) geometrica Agassiz,1838 ; Salenia (Salenia) leanderensis Ikins,1940 ; Salenia (Salenia) scotti Ikins,1940 ;

23/01/2009 Just a little word about a (little) mistake I have done when constructing the page dedicated to Arachnoididae. For Fellaster incisa, the real reference is (TATE,1893) and not at all SADLER & PLEDGE,1985. A friend of mine, who lives in Australia pointed it out and report it to us : a big thank to him, great connoiseur of Aussie echinoids. with this update, I will continue the serie of Rhynchopygus with another two specimens from my friend "Sarthacensis". The first one is the type species of the genus. Just have a look folks...

Rhynchopygus marmini (Agassiz, 1847)
Rhynchopygus savini (Cotteau, 1894)

03/01/2009 One more time and as we use to say in France : "jamais deux sans trois". This is why you've got a third message today. For this issue, are concerned :

The second exemplar kindly provided by a friend of mine (J.-F.D., also called "Sarthacensis" on some internet forums). We add also a new species of Rhynchopygus (Faujasiidae) : Rhynch. gauthieri (de GROSSOUVRE), it comes from Sartha's collection too. I hope that you'll be informed today again about another new galleries, if I've some time to waste with fossils...

27/12/2008 Let's add some new specimens in the schizasterids collection with : Schizaster armiger, S. depressum, S. ocalanus, S. rimosus.
