https://t.co/ip5fk2552i A great news story and even Mary Anning loved fossil crinoids! Given with the author’s compliments no less.

Happy curator washing a new, spectacular piece of crinoidal limestone from the Early Carboniferous/Mississippian (360million years old) of Derbyshire, UK. This will form part of the new garden displays at the NHM London. Check out these huge crinoid stems!

OH NICE! the brisingid Astrocles, a new record for the Aleutians Islands! 2804 m #okeanos Lone Knoll

[Tim Ewin @tim_ewin]

@marine_fau Talk to some who has done fieldwork there before!

[Tim Ewin @tim_ewin]

@Tweetisaurus 😂🤣 only thought is that Scooby doo had a friend called something like that no?!

[Tim Ewin @tim_ewin]

Some awesome broody starfish with cute baby starfish!

[Christopher Mah, @echinoblog.bsky.social @echinoblog]

Starfish bearing young (brooding) is a CRAZY thing. Most species live around the Peninsular region. But there's like 5? 6? DIFFERENT lineages/groups that ALL brood in DIFFERENT WAYS. Young around mouth. Internal brooding. Brooding among arm spine baskets!

#fossilfriday More beautiful Wiltshire Middle Jurassic crinoids! Those lovely long stems are being used for an exciting research pilot study into biometrics and ecological tiering! Can you spot the starfish as well?! (Tip: look towards the bottom!)

[Tim Ewin @tim_ewin]

Congratulations @NHMdinolab! As you say a very appropriate dinosaur to be named after you! Nice one @Tweetisaurus !

Some stunning crinoids from Canada. The large tongue-shaped extension in the cream coloured specimen is a huge anal pyramid! This may also be where the gonads were located (hence large size) and differs from modern crinoids where they are located on the arms.

Assorted crinoids from the Royal Ontario Museum Dawn of Life gallery this #FossilFriday.
Despite being commonly called "sea lilies", crinoids are echinoderms (one of the more interesting groups I don't work on, which includes things like sea urchins).

@MarvelShark42 It’s a great site!

[Tim Ewin @tim_ewin]

It’s on!

[Clare Fisher @Bruchlas]

It’s our 2nd visit behind the scenes @NHM_London at 8pm @channel5_tv. @tim_ewin investigates a 167 myo ‘marine Pompeii’. @SelBrace collects DNA from a bee’s knees and @ChrisGPackham takes to the stage for the Wildlife Photographer of the Year & Hattie takes us to a haunted lift!

@Bruchlas Thanks for sharing this I’d not seen it!

[Tim Ewin @tim_ewin]

Never thought my mug would be featured in the Radio Times magazine! Check out some of the beautiful fossils we’ve collected and the research we are undertaking on them on Channel 5 at 8pm this Wednesday!

[NHM_Bryozoa @BryozoanNhm]

#FossilFriday Another fossil from the Palaeogene Red Bluff Tuff of Chatham Island – a small, flat-topped spine from an echinoid.

Am on a Channel 5 episode in a series exploring the work the natural history museum does. It features the Wiltshire fossil site (that contains thousands of exceptionally preserved echinoderms) and some of the research we are doing.

[Tim Ewin @tim_ewin]

The coordinated behaviour of tube feet along an Ophiuroid arm is fascinating to see. Love how the tube feet immediately go back to food capture again after they’ve passed the parcel!

アカクモヒトデ Ophiomastix mixta Lütken, 1869の摂餌行動です。管足を上手に使って餌を口の方向に移動させています。まるで運動会の大玉転がし（送り？）みたい。

[Tim Ewin @tim_ewin]

Absolutely love this!
