TqB Posted October 26, 2017 Share Posted October 26, 2017 Three productids with most of their spines intact, showing that they looked like hedgehogs. I haven't identified them further largely because I can't see the shells properly. (Edit: likely to be Echinoconchus or similar echinoconchid - see below) These are from a Brigantian (Mississippian) mudstone in NE England, Co.Durham. 1) About 6cm across 2) Interior brachial valve showing spines projecting around the edge from behind. About 3cm across. 3) about 4cm across: 4 Tarquin Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted October 26, 2017 Share Posted October 26, 2017 How wonderful. I must get some spiny productids. And beautiful photographs too. (ahem) Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

ynot Posted October 27, 2017 Share Posted October 27, 2017 I have heard of "bearded clams" before, but this is the first I have seen! Nice finds. Darwin said: " Man sprang from monkeys."

Fossildude19 Posted October 27, 2017 Share Posted October 27, 2017 These are incredible, Tarquin! Very rarely see spines on brachiopods from areas I've collected at. Thanks for posting these - a treat to see them.

Archimedes Posted October 27, 2017 Share Posted October 27, 2017 Very nice find.... looks to be an Echinoconchus, they are very common in the upper Mississippian in eastern north America. 1 Link to comment Share on other sites More sharing options...

TqB Posted October 27, 2017 Author Share Posted October 27, 2017 Thanks all for the kind comments! @Archimedes Thanks, Echinoconchus looks very likely - I also had Pustula as a possibility which may be a synonym if @doushantuo's Gobbett reference is current. Ben, great outtakes, I'll try to find the papers. I guess those stunners in the Grant plate are silicified? Tarquin Link to comment Share on other sites More sharing options...
doushantuo Posted October 27, 2017 Share Posted October 27, 2017 Tarq,see the legend to figure one If ayone has either Orrhage(Zoomorph./1973) or Carsten Lueter 's 2000 Anat.

But had to especially thank you for the bluebird pictures. My wife and I love bluebirds and love to learn about them! Will have to research this a little more as I had never heard of this.

doushantuo Posted October 27, 2017 Share Posted October 27, 2017 Minn,the reason for those in my signature are very plain & simple: i've been reading a lot about the comparative morphology of bird skulls and vertebrate cranial kinesis in general,and the more extravagant examples always draw my attention. Papers on trochilid functional morphology(--->>>"what makes hummingbirds tick") are rare Edit: From Vellutini et al.,2016 Link to comment Share on other sites More sharing options...

minnbuckeye Posted October 27, 2017 Share Posted October 27, 2017 Sometimes one types and does NOT look at what one composes. Here is a prime example where proof reading would have caught my mistake. I was out cleaning out my bluebird's houses yesterday and without thinking, wrote bluebird instead of hummingbird. Yes we prefer hummingbirds to bluebirds. Thanks for pointing out the mistake!!!

Brittle Star Posted October 27, 2017 Share Posted October 27, 2017 Wonderful photos Tarquin, we both have the same specimens so now I know what to call mine.

Bobby Rico Posted October 28, 2017 Share Posted October 28, 2017 Thanks for showing us Tarquin some great detail shown on the spiny brachiopods . Very crisp with good contrast, you have a good lens there. I have never seen this brachiopod before it's really strange but beautiful. Also @doushantuo post are very interesting too. Cheers Bobby Link to comment Share on other sites More sharing options...
RJB Posted October 28, 2017 Share Posted October 28, 2017 Looks like ive got a newfound respect for the lowly brachiopod. Very cool fossils! RB Link to comment Share on other sites More sharing options...
