This weeks #Lego #FossilFriday is #Umoonasaurus

In 1987 an opal miner in Coober Pedy found an opalised fossil. They were part of the Zorba Extension Opal Field.

In 1988, the chairman of the company Comrealty ("Mr. Sid Londish") bought the specimen. Later that year he donated it to the Australian Museum.

In September 1988, it was prepared by the Australian Museum.

In 2006, Benjamin Kear and colleagues named Umoonasaurus, part of Pliosauroidea and the most basal Rhomaleosauridae.

Horses vanished from North America ~10,000 years ago. So why are these fossilized teeth turning up across the Midwest

A friend found the infamous “black tooth” back in 2018 — and now we’re waiting for the radiocarbon dates. No dates have previously been documented!

Will they point to the Ice Age, or something pre‑European contact? 💬 Share your thoughts — what do you think the dates will reveal?

Ein #Sammlungsstück zu den heutigen Hashtags: Kein echtes #Fossil - subfossil, noch nicht #versteinert , aber dabei 😁

Ein gut 6.000 Jahre altes Stück #Holz 🪵 aus der #Elbe in Tschechien, bei dem man die #Jahresringe als hellere und dunklere Linien erkennen kann. So kann man nicht nur die vorgeschichtlichen Temperaturen 🌡️ ablesen, sondern per #Dendrochronologie auch das Alter bestimmen 🧙‍♂️

This week’s Fossil Friday is a pair of enamelled gar scales. Gars are ray-finned fish whose bodies are covered in tough, often shiny scales; the enamelled surface helps protect them and gives many specimens a distinctive look in the field and in collections.

These scales were collected from Red Rock Coulee in 2006 by Hope Johnson. They are catalogued as APS2006.050.

This week for #Fossilfriday we have another #Guess that #Lego #Fossil.

This one I would rate as hard. This opalized marine reptile fossil is on display in the front window of a shop in Adelaide, South Australia.

Hide your guesses behind a content warning, so others can guess without being spoilt. I will post the answer tomorrow (and to anyone who guesses correctly).

The was designed by mindbox, and ngl its not super accurate.
