#Gorgosaurus ( GOR-gə-SOR-əs; lit. 'dreadful lizard') is a #genus of #tyrannosaurid #theropod #dinosaur that lived in western North America during the #LateCretaceous #Period (#Campanian), between about 76.5 and 75 #millionYearsAgo. #Fossil remains have been found in the #CanadianProvince of #Alberta and the #USState of #Montana. #Paleontologists recognize only the #typeSpecies, G. libratus, although other species have been erroneously referred to the genus. Like most known tyrannosaurids.

How to Make a Mammal in Nine Evolutionary Steps https://www.smithsonianmag.com/science-nature/how-to-make-a-mammal-in-nine-evolutionary-steps-180985289/ by Riley Black

"#Paleontologists have known for decades that #mammals emerged from a broader, diverse group of creatures called #synapsids... Nevertheless, a big evolutionary gap exists between a very early, lizard-like synapsid and modern mammals like ourselves."

Therapsids Originated in Tropical Rather than Temperate Regions https://www.sci.news/paleontology/mallorca-gorgonopsian-13515.html

Early–middle Permian Mediterranean gorgonopsian suggests an equatorial origin of therapsids https://www.nature.com/articles/s41467-024-54425-5

"#Therapsids were a dominant component of #Permian terrestrial ecosystems, eventually giving rise to #mammals during the early #Mesozoic... #Paleontologists have discovered a #NewSpecies of early #gorgonopsian #therapsid that was part of an ancient summer wet biome of equatorial #Pangea"

#Paleontologists have long puzzled over how the dinosaurs—originally relatively small and of minor importance to the broader ecosystem—evolved to become the dominant species some 30 million years later. Fossilized #feces and #vomit from #dinosaurs might hold important clues to how and why this evolutionary milestone came about, according to a new paper published in the journal Nature.

#Testosterone in tusks: #Hormones in #mammoth #fossils excite #paleontologists
There’s a lot we can correlate #hormone levels with, because #proboscidean tusks record the life of that animal. Its rings record days and years of growth, for example, seasons in which it experienced famine or abundance, from when it was born to when it died. So if further information, such as additional hormones, can be detected, this opens up a new window into the lives of #extinct #species
