I work on #dinosaurs, but you'll see all kinds of #fossil pics. Everything I post here gets retweeted at @paleontologizin, so maybe follow me there instead!

If you still use "dinosaur" to mean outdated, rather than something with great staying power and adaptability, you may be outdated yourself.

Because I never get tired of this lovely critter, here's a dentary of #Dilophosaurus for this week's #FossilFriday. Like most stuff in this fm., the preservation isn't too pretty, but man what a beautiful jaw

[Danny Anduza @DannyAnduza]

Let's give some love to a kickass plant for #FossilFriday! Here's Metasequoia, the "dawn redwood," which was best known from #Mesozoic fossils...

...until the 1940s, when Chinese researchers discovered *LIVING* examples in southern China.

Ground sloths are BIZARRE! Here's a hand claw from the bigass Paramylodon (aka Glossotherium to some), dug up right here in California. This is *not* the maximum size for their manual unguals, btw.

Here's a Duriavenator maxilla cast, with a lovely inside view of the tooth roots. This genus used to be in the good ol' Megalosaurus wastebasket, when it was previously known as M. hesperis.

Sick of turkey after #Thanksgiving? OH WELL! Here's a leftover humerus of Meleagris gallopavo 🦃 for #FossilFriday. This specimen from @ucmpberkeley hails from the #Pleistocene of CA and thus would have gobble-gobbled alongside mammoths, ground sloths, and saber-toothed cats

[Paleontologizing (w/ Danny Anduza) is on Bluesky @Paleontologizin]

I needed a last-minute #Thanksgiving T-shirt design, so here's a "six-foot turkey" for all you #JurassicPark nerds. #HappyThanksgiving to all!

For this week's #FossilFriday, here's a skull cast of Eoraptor! One of the earliest dinosaurs known (dating back to about ~230 million years ago), Eoraptor is so primitive that researchers still aren't certain whether it's more closely related to theropods or sauropods.

[Danny Anduza @DannyAnduza]

For this week's #FossilFriday, here's the world's best-preserved Dilophosaurus skull, right here at @ucmpberkeley. Years ago I helped stabilize that head crest in the lab, and it is PAPER-THIN. Really bizarre to see such a delicate structure on such a badass carnivore

[Danny Anduza @DannyAnduza]

Here's the lower jaws of an American lion, Panthera atrox. This individual prowled #LosAngeles between 10K and 20K years ago, when the area was home to a spectacular and diverse array of giant #mammals, on par with Africa's Serengeti -- right here in #California!

[Danny Anduza @DannyAnduza]

Just your periodic reminder that #mastodon teeth are really cool and weirdly human-looking

[Danny Anduza @DannyAnduza]

Gigantic #Triassic #phytosaur skull on #FossilFriday. These 'pseudo-crocs' played the #crocodile role and lived all over the globe before the true crocodiles took over. Here's to a little phytosaur recognition for #CROCtober!

[Danny Anduza @DannyAnduza]

An isolated Dilophosaurus tooth, collected by Sam Welles in Arizona, 1964. Although #Dilophosaurus is well-represented in pop culture, skeletal remains of this dinosaur are actually fairly rare, with only a few specimens known. This particular one is cared for at @ucmpberkeley

[Danny Anduza @DannyAnduza]

Hand in hand with Lucy for #FossilFriday! Discovered in #Ethiopia in 1974 and named for the #Beatles song (you know the one) this 3.2 mil-yr-old Australopithecus specimen helped piece together the story of #humanevolution. This hand is just a cast, but still kinda magical to hold

[Danny Anduza @DannyAnduza]

#HorseFace has galloped into the #trending hashtags because of something some jackass tweeted... so neigh, I could not resist ponying up with a #fossil #horse. Here's most of the skull of a beautiful Miohippus from @JDFossilBedsNPS

[Danny Anduza @DannyAnduza]

Here's yet another #Triceratops horn for #FossilFriday. As the most common large animal in the #HellCreek Formation, hundreds of these critters have been excavated, and I've personally dug up about a dozen. This one was collected by the legendary Harley Garbani in 1983

[Danny Anduza @DannyAnduza]

Dug up during construction of @OAColiseum in 1964, here's the tooth of a Columbian #Mammoth. Though named for #Columbus, I want to point out that mammoths like this one actually lived alongside the Americas' original human inhabitants

Juvenile #Trex skull cast for this week's #FossilFriday. Note the number of teeth in the lower jaw -- as #Tyrannosaurus grew and matured, their teeth got larger, thicker, and less numerous, suggesting a change in diet throughout their lifespan.

[Danny Anduza @DannyAnduza]

#RodentWeek scurries onward! Here's a skeleton of #Neotoma, a modern #packrat. I've encountered these little guys many times when doing fieldwork in the #HellCreek -- they love to build middens in our #dinosaur quarries at night, especially under #Triceratops frills

[Danny Anduza @DannyAnduza]

It's #RodentWeek 2018! I don't really work on #mammals, but that doesn't mean I can't appreciate them! Glued to the end of that pin in the vial is a tiny tiny tooth from Copemys, a #smol mouse from California's Barstow Fm., about 18 million years old.

[Danny Anduza @DannyAnduza]

Here's a thoughtful thank-you note from some cool 2nd graders at @TheSaklanSchool. Sounds like they really enjoyed the #dinosaur tour last week! 🦖
