Pulga del Cenozoico que quedó atrapada en el ámbar hace 20 millones de años. En su probóscide contiene lo que se cree una cepa ancestral de Yersinia pestis, regurgitada porque forma una masa viscosa en el proventrículo, impidiendo que se alimente de sangre. 📷George Poinar, Jr. #cenozoico #cenozoic

Morphological innovation did not drive diversification in #Mesozoic–#Cenozoic brachiopods https://www.nature.com/articles/s41559-024-02491-9

#Brachiopods were evolving in new directions but this did not become an evolutionary success in terms of the numbers of species... The findings shed light on some core principles of the #evolution of modern #biodiversity.

Electroscincus zedi: Compound Osteoderms preserved in #Amber reveal the Oldest Known Skink https://novataxa.blogspot.com/2024/07/electroscincus.html

"#Scincidae is one of the most species-rich and cosmopolitan clades of squamate #reptiles. Abundant disarticulated #fossil material has also been attributed to this group, however, no complete pre-#Cenozoic crown-scincid specimens have been found. A specimen in #Burmite (99 MYA) is the first fossil that can be unambiguously referred to this clade."

Three New Species of #Fossil Kangaroos Discovered in Australia and New Guinea https://www.sci.news/paleontology/protemnodon-kangaroos-12857.html

Systematics and #palaeobiology of #kangaroos of the late Cenozoic genus Protemnodon (Marsupialia, Macropodidae) https://mapress.com/mt/article/view/megataxa.11.1.1

"The three #NewSpecies belong to the extinct #kangaroo genus #Protemnodon, which were common members of #Cenozoic communities across #Australia and #NewGuinea until their #extinction in the Late #Pleistocene."

[as a geologist and an adventure rider – and a Colorado resident that loves history - I have travelled all over this area; first photo is mine, my motorcycle under the Apishapa Arch in Aguilar, Colorado, a 1930s Civilian Conservation Corps project through a volcanic dyke, ‘coincidentally’ providing better access to land that a senator had purchased up around Cuchara and Cordova Passes]

"We explore the #Mesozoic to #Cenozoic Patagonian #Andes #tectonic evolution, combining U-Pb zircon ages, bulk rock εNd, and new detrital #zircon εHf from the retroarc basin to understand the associated magmatic arc evolution during retreat and advance of the margin. Our results reveal a protracted phase of isotopically juvenile magmatism between 150 and 80 Ma, which began during backarc extension and persisted long after the margin switched to a contractional regime."

An Agnotherium I painted for the museum Tor zur Urzeit. Agnotherium is a Late Miocene bear dog from Eppelsheim. I based most of the anatomy on the related Ammitocyon, due to the fragmentary nature of Agnotherium remains.

A modern sand tiger shark (Carcharias taurus) and its 5 m long relative Carcharias cuspidatus from the Oligocene. The size is known from a partial skeleton that was found near Rauenberg in Baden-Württemberg.
