Barton Gastropods

Hi 'ynot' Eocene  Barton is Bartonian 38.0-41.3(Ma). The block is probably derived from an A3 shelly lens. Here's one such lens pictured below. Sometines you get a block in them.

 

Quite a lot of life recorded in the one above  it, Scaliola sp.,  Dentalium bartonense, Rimella rimosa, Venericardia sp. Coral Turbinolia sp. Sharks teeth Striatolamina macrota (Agassiz 1843) to name a few.

I Thought it would be good to show you some pictures of the Location 

A little warning letting you know that you can get stuck in the mud quite easily.

Really beautiful your Hippochrenes, I returned yesterday from Barton, unfortunately I have not found. The terrain was very dry, but better finds in the past was in heavy rain.

Yes it's been dry for the last week or so. It was a bit better last week but with half term lots of footprints just one small sharks tooth and gastropod worth picking up for me. The formation is much collected these days certainly more so than when I first started collecting.

Thanks all for your kind comment's. Yes Tidgy' Dad The mature ones are very difficult. Would like to see what you have from Barton???

 

There were two of us on the Beach during a Storm Surge when that last one came, mad we are! Saw a hint of it, then partially exposed it. Suspected it was good protected it with mud and dug a block out for safe extraction in better surroundings. Thirty plus years of waiting just goes to show all comes to those who wait serendipity certainly smiled on me that day. I have seen many similar tales on the forum.

 

Now just trying to find one which is showing a transition from Juvenile to adult. I can't believe they put the wing on in such a short term.

 

A block for you all to look at

I agree with you David, for the devellopement of the labre that it is a rather long process.
Photo of Tibia dewalquei close to the species Hippochrenes Amplus, which shows the evolution of the labre, especially on the 5 th which shows many outgrowths of the labre, and this one is not hung up at the apex
We can meet copies with a smaller body already labré than a juvenile with a larger body, can be a question of sex

Thanks Vincent I have found smaller fragments  which bear this out they are very fragile so to find a compete one would be special indeed.

I thought I'd post some more. pictures

This one shows a Clavilithes pinus  [Clavilithes macrospira] pictures right with an odd Clavilithes sp it's clearly different and not crushed.

I don't wish to give the impression that there are only gastropods to be found at Barton. As you all know the Eocene was teaming with life. So here's some pics to show some of the other life which was present.

Sharks  in the main sand tigers. and they got quite big.

This has been a very informative thread.  I must confess to not knowing much about gastropods but have been collecting shark teeth for a while.  I traded with a Barton collector years ago so I have a sample from there.  It appears Striatolamia macrota reached its largest size during the Bartonian and then disappears.  I've seen a few of that size shown from there and from at least one site in Kazakhstan.  Those are nice Jaekelotodus too.  I assume it's at least uncommon to find one there.
