Cothurnocystis elizae is an asymmetrical echinoderm from the Lady Burn Starfish Beds (Scotland, ~440Ma). 'Cothurno' is from the latin for boot, based on the unique shape of its theca, 'elizae' is after fossil collector Elizabeth Gray who collected many specimens in the early 1900s
#FossilFriday
An asymmetrical fossil echinoderm preserved as a mould. It has a boot shaped theca and an anterior feeding appendage. It has multiple openings on the dorsal side of its theca used for respiration. Scalebar increments = 1mm, specimen is ~5cm long in total. There is also a small trilobite cephalon in the rock.

I want to ruin biblioteca for you all too
spermatheca / theca — The queen’s sperm-storage organ. Theca from Greek θήκη = “a case, box, receptacle,” from τίθημι = “to put, set, place.” A theca is a container, a placing — the queen’s body literally places the seed into storage. For Ch. I, the egg chamber IS a theca. And bibliotheca shares the root — the library is a book-theca, the queen is a sperm-theca, the embedding layer is a vector-theca.

A modern glass building with a large cloud-like structure inside. The sky is cloudless and bright blue and is reflected in the facade of the building so that the entire structure appears blue as well.

We strongly suspect that the fish made their unsuccessful attempts when the blastoids did not have their brachioles deployed.

Maybe a better way of phrasing that is that I HOPE not, because just look at the options here:

Blastoids are echinoderms, related to starfish, sand dollars and crinoids. They are usually very small and the thin stem and hair like brachioles are usually missing. The bulb like theca is usually the only thing found.

This is Devoniblastus from Arkona, Ontario.

I talked about some of the stunning botanical books in the Teylers collections on day 2 of VisionLab! We focused on the various book formats and how the physical sizes of the picture planes affected the depictions of plants & microscopic observations. #VisualizingtheUnknown
Hand-colored engraving of a crown imperial flower and bulb from Basilius Besler's Hortus Eystettensis (1613). Tab. 56 that depicts the backside of the Theca, the belly of the Theca, the column of the magnifid, flower of Hyoscyanus, one of the spermatick Thecae, the edges of the Theca open, and the column in the middle of the flower. From Nehemiah Grew's The anatomy of plants (1682). Hand-colored etching of various parts of wheat in the Blackwellianum Herbarium (1750-1773).

Blastoids, an extinct group of stemmed echinoderms (marine invertebrates related to starfish & sea urchins) that lived from the Silurian to the Permian depicted in Kunstformen der Natur
(1904) by Ernst Haeckel. Echinoderms are the only animal phylum with pentamerous symmetry. 🦑

An illustration of a variety of blastoids, many depicted from the top view of the base of their theca highlighting their pentamerous symmetry, some looking like five pointed stars. #fossils #sciart #oceanlife

We come back to our Cambrian fossil, Atlascystis, ancestral to modern echinoderms. It has bilateral symmetry but radial bone-like plates (ctenidial plates).

These radial plates have a developmental parallel in starfish arms, which also develop radially, outward from the central mouth.
(A–C and E–G) NHMUK EE 19394. (A and B) Ventral and dorsal views, respectively, of the complete specimen. (C) Ctenidium and anterior theca in ventral view, with ctenidial plates highlighted. (E) Lateral spines in ventral view. (F) Right ctenidium and anterior theca in dorsal view. (G) Posterior spines in ventral view. (D) NHMUK EE 15324a(1). Ventral view of the complete specimen, with ctenidial plates highlighted. (A, B, and D–G) Latex casts whitened with NH4Cl sublimate. (C) Virtual reconstruction. ct, ctenoid plate; di, dorsal integument; dt, dorsal tessellate plates; ls, lateral spine; oo, oral opening; pp, periproct; ps, posterior spines; rp, ridged plates; sb, suboral plates; sr, suroral plate; and vi, ventral integument.
