Help please. Some time ago. there was a thread in which some one I believe from the northeast USA commented on their finding various shark egg cases. I have tried searching in vain to locate that post. I volunteer at the Natural History Society Of Maryland. I am trying to put together a display/talk for shark week coming up in July. Would like to include recent shark egg cases along with my collection of fossil shark teeth and centra.  I can trade various Miocene/Pliocene fossils, St Clair ferns or other fossils. Any help to connect me to anyone with shark egg cases would be greatly appreciated

Coco's collection, and her post, is terrific. I have some skate egg cases (Raja sp.) I'd be glad to send you, if you want them, but I don't have any sharks.

lordpiney  In looking @ Coco's post on shark egg cases, I saw your response re finding them. See my original post above. Any help you can provide, I would appreciate. PM me and we can work out any details. Thanks for your consideration.

Pagurus  Thanks for your kind offer. I already have a number of skate egg cases from both NC and SC. But would like some shark-shark ones to add to the display

less than 2,5 Mb,and an awesome addition to anyone interested in the ecology of hydrothermal vents & /or selachian repoduction

edit(POST-Pagurus reaction):

ok,I'm guessing the biomimetics crowd is active again:spider silk analog,elastic,yet strong->selachian egg case lit hard to get,at least the ones focussing on functional morphology.

Shark & ray conservancy might have something to woith it as well

Will try to get Knight's 2008 piece in Biol.Rev,but am pessimistic as yet(paywalled)

Hi,

 

I have a lot of recent shark and ray eggs, but I think I have only one species of shark eggs : Scyliorhinus canicula. I can send you several of each species I have a lot. Just let me know, it would be done with pleasure.

@Coco It is not clear who if anyone in particular you meant to receive this offer. I am very interested in shark egg cases as I explained in the initial post. I would be pleased to work something out with you. Just let me know. I am trying to learn to distinguish shark from ray eggs. The horn shark ones are very distinctive but other do not seem that different from rays. I am just starting to learn. In an event, your posts are very informative and you have an outstanding collection.
