Graptolites under the scanner
Fossil graptolites (Orthograptus) preserved as silvery markings on black shale
Animals drifted in oceans hundreds of mn years ago

Some of the incredible #fossils from the Fezouata Formation seen on my recent trip to Morocco. #FossilFriday #Ordovician #trilobite #graptolite #radiodont
A beautifully preserved dendroid #graptolite from the Cat Head Member, Red River Formation. Graptolites are an extinct group of hemichordates, a little-known phylum related to #echinoderms and #vertebrates!

Over just a few centimeters, the #graptolite communities of the Želkovice locality change significantly! A new study reveals diverse, well-developed communities and several previously unreported species in the Prague Synform.
Database of #graptolite genera through time from the Treatise on Invertebrate #paleontology #palaeontology now available! https://t.co/25TbR7PQ2W
The @paleoinstitute has added another database to our website: #graptolithina genera in space and time, extracted from Part V, Hemichordata, 2nd Revision, 2023.

Here is a #graptolite drawn by Professor Charles Lapworth, who recognised these #fossils could be used to correlate #rock sequences through #mapping and biostratigraphy, vital to understanding an area's geological structure and history!

Throwback to how geology students once learned about graptolite morphology! This teaching aid was used at @unibirmingham in the early 20th century. Try to zoom in and spot some of the features!

Watch this gorgeous and amazing 3D #graptolite fossil! A dendroid of the genus Callograptus, from the #Devonian of #Belgium. Figured in our new paper in Annales de Paléontologie #naturalsciencesbrussels #FossilFriday https://t.co/GZ5Hh1Nrfy

A new Ordovician lagerstätte has been described today! We get the scoop on this exciting new site in Wales!

In this 1st experiment on colony and tubarium development of a living #graptolite, we found that Rhabdopleura recondita requires a bryozoan host matrix for colonial development & its tubes show no phenotypic plastic response to water flow velocity. https://t.co/56naQnztlx
What is @palaeo_anna looking at down the microscope? If you’re at @ThePalAss #PalAss22 this week, check out Anna’s poster exploring the possible origins of enigmatic structures associated with #graptolite #fossils from northern Vietnam 🇻🇳🐚
Our last objects of the week post to celebrate Geo Week features Mollusc and Graptolite. Can you guess which one means "writing in the rocks" in Greek?✏️

Day 6, and a total #graptolite bonanza at the Blue Lagoon, Abereiddy Bay. Never seen so many Didymograptus, they must have been waiting for us to return this past three years @GeologyLeics
#Graptolite #fossils look like black pencil marks.
These are former living quarters of an entire colony of animals.
In the grooves on either side is a cup where an individual animal lived.
Visit us to see #graptolites in person with our touch #fossil on exhibit!

Rhabdopleura is a living #graptolite. Only 5 species are known, so the discovery of one in Singapore is 😊
3 #NewSpecies of Bryozoa + 9 new records of Bryozoa + 1st record of class Pterobranchia in #Singapore, by @SudhanshiSJ DennisGordon @lhliow et al. @lkcnhm @ResearchFos

The pterobranch: Rhabdopleura👇. And the #NewSpecies...
Check out these #Graptolite fossils this #FossilFriday!
Notice the structural differences between the #fossil on the left compared to the #fossils on the right?
They appear to be different species...
#Graptolites began to develop rapid diversity during the #Ordovician period.

A #graptolite seen under magnification care of a Celestron Digital Microscope #fossil #fossil #paleontology #macrophotography #NaturePhotography #nature
My personal favourite is the #Graptolite. It's such an unusual fossil and nobody else has one as an emblem. The Victorian graptolites from the Ordovician period are world-famous - so much so that many of our species are used worldwide to correlate different rocks.
