Spined Echinoid

[sharko69]

A few weekends ago I went to Texoma with the family and found a bunch of crushed Echinoids. Looking at them

today, I noticed that one has what appears to be the spines still remaining. That leaves me two questions: 

 

Are these spines? And how common is it to find them with spines if that is indeed what they are?

 

As always. Thank you for the insight.

Echs with the “5 o’clock shadow” are always desirable to collectors in the know.  Well done.

That's a cool find!

Congratulations.

Neeto!

Those are some very short spines!  I have never seen a urchin test like that with the  spines flattened all over them. Awesome find.

Wow that's a good one!

Thank you. Collected them a few weeks ago. Went to the eye doc and got progressive lenses last week so I don't have to wear glasses while hunting. I was about to put them in my pile I donate to the schools, when I saw the spines. Contacts are obviously working. Wonder what I have walked past the last couple of years??

Nice find! If you google Landaville Seeigel (which means sea urchin) you'll discover some nice ones from a well-known site in the north of France.

Thanks. Came up in Danish. Good thing I studied Nordic Languages at Istitatutionen för  Nordiska Språk in Sweden.

Thanks. May have to look a little closer at these moving forward.

Yes, very nice fossil. Not unheard of but not common either. I always pick up loose spines. Some locations will have just the echinoid tests, some will have tests and scattered spines, on occasion I find many different spines but none actually with the test. The two together is bonus.

That is a really nice find. Archaeocidaris echinoids with their spines can be found at the Brownwood spillway at Brownwood, TX.

Nice one. To add to the pile of occurrences, I have found similar echinoids with flattened spines at my local Upper Cretaceous site here on Vancouver Island, though mine are a little less obvious so might be a little more difficult to photograph.

Always great to find echinoids retaining some or all of their spines, also very rare. I often take my sand encrusted echinoids from one particular location and let them weather outside. Occasionally the rain exposes spines on some of them. If you look in the collections section for echinoids I have 2 very nice spined echinoids in there.
