Fossils, Limestone And Salt: Hallstatt

Fossils, Limestone And Salt: Hallstatt

Mar 24 2024 | comment(s)

Hallstatt Salt Mines, Austria / Permian Salt DiapirThe Hallstatt Limestone is the world's richest Triassic ammonite unit, yielding specimens of more than 500 ammonite species.


Along with diversified cephalopod fauna  — orthoceratids, nautiloids, ammonoids — we also see gastropods, bivalves, especially the late Triassic pteriid bivalve Halobia (the halobiids), brachiopods, crinoids and a few corals. We also see a lovely selection of microfauna represented.

Decapods: Warrior Crabs

Aug 24 2021 | comment(s)

Look how epic this little guy is! He is a crab — and if you asked him, the fiercest warrior that ever lived. While that may not be strictly true, crabs do have the heart of a warrior and will raise their claws, sometimes only millimetres into the air, to assert dominance over their world. 

Crabs are decapod crustaceans of the Phylum Arthropoda.

Crinoids: Beauties Of Echinodermata

Crinoids are unusually beautiful and graceful members of the phylum Echinodermata. They resemble an underwater flower swaying in an ocean current. But make no mistake they are marine animals. Picture a flower with a mouth on the top surface that is surrounded by feeding arms. Awkwardly, add an anus right beside that mouth. 
Late Cretaceous Fauna: Colinoceras Tarrantense

Late Cretaceous Fauna: Colinoceras Tarrantense

Previously Calycoceras Tarrantense, this ammonite is now Conlinoceras tarrantense after J.P. Conlin, a famous early 20th-century fossil collector from Texas, USA.

Ammonite expert Bill Cobban used this collection to describe many Texas Cretaceous ammonites species including this species from Tarrant County, Arlington, Texas. He was a surveyor by training and kept incredibly detailed notes on the context of his fossils.

Living Fossils: Winning The Slow Race Of Time

Aug 23 2021 | comment(s)

Horseshoe crabs are marine and brackish water arthropods of the order Xiphosura — a slowly evolving, conservative taxa.

Much like (slow) Water Striders (Aquarius remigis), (relatively sluggish) Coelacanth (Latimeria chalumnae) and (the current winner on truly slow evolution) Elephant Sharks (Callorhinchus milii), these fellows have a long history in the fossil record with very few anatomical changes.
