- Reposted by Tim DemkoRoger Benson sent me some amazing CT segmentations of one of the recent fossils found by our team in the Middle Jurassic of Skye & they are incredibly exciting. This is why it is worth being a palaeontologist: the utter joy of the new and unexpected discovery.

- Reposted by Tim DemkoScientists just found that a curious group of plankton began to flourish rapidly after the dino-killing asteroid—a key sign life was on the mend. They made their discovery by measuring the slow accumulation of space dust after the impact. #Paleontology #PlankticForams New for @science.org 🧪🏺

- Reposted by Tim DemkoDickinsonia, back when evolution was excited to make pancakes. Paleontologists are pretty sure Dickinsonia was an animal, a creature that lived in the sea around 550 million years ago. The flat, ripply organism adhered itself to the floor with mucus and grazed on mats of microbes. Slick. 🧪

- Reposted by Tim DemkoReally SVP? You’re just going to ignore decades of sexual and academic misconduct, marrying a student AT one of your conferences, and every report I’ve filed (implying that’s what you do with reports) to defend famous Horner? You’d rather have pedophiles than students is your message?
- Reposted by Tim DemkoI gotta say though... they've known about this person's behavior for *decades*. I first heard rumours of it on my first trip to the US in 2005! Why would they act now, rather than that time he married *his own undergrad?*
- Is @societyofvertpaleo.bsky.social being serious here? No, the presence of a name on an email doesn't establish wrongdoing. But the *content* of those emails is what so many members, including myself, are outraged about. This response does nothing but further degrade my confidence in SVP leadership
