If you look closely at tide tables, the day-to-day variations are pretty strange.

Of course the big paper on Azhdarchoid phylogeny comes out while I'm at a museum on a research visit (looking at Azhdarchoid cervicals, obviously) but now I'm back at the hotel so it's time to write a proper thread! 1/28

Today's #Nudivember is Cerberilla tanna. I try to approach each species as they come, but I am a fan of Cerberilla species. Their striped cerata are very cute.

Lucky to get some brief glimpses of Comet Lemmon (C/2025 A6) from Dartmoor this evening around the end of astronomical twilight. This is a single 13s shot taken with a tracking mount at 135mm focal length.
Looked great in binoculars too with a grey-green coma and short section of the tail visible.

In parts of Michigan, you can pick up a fairly ordinary chunk of limestone & with some polishing, reveal a coral formation that was laid down when this area was a tropical sea in the Devonian, 350 MYA.
These are Petoskey stones, the state stone of Michigan.

Given recent interest in the ankylosaur, Spicomellus & its extreme armour, I thought l'd share this photo of an #aetosaur spike for this #FossilFriday. Highlights how wonderfully weird #Triassic reptiles pioneered many striking traits once thought limited to dinosaurs.

Flyby success! ESA's Juice spacecraft passed Venus at 07:28 CEST on 31 August.
This photo shows our deep-space antenna in Spain in communication with Juice during the flyby.
Juice’s current location, Venus, and its destination, Jupiter, are both visible in the sky ❤️

This is likely the last blazing hot week at the northern edge of lizard-dom. The Mountain Short-horned Lizard will be soaking up the late summer sun before their long idle winter season. #herps

Clarification: when I say “X animal make terrible pets for most people”, what I really mean is that most people are terrible and wouldn’t be able to do right by that animal, not that the animal is terrible.

I have a semi-leucistic Black-capped Chickadee that comes to my backyard fountain once or so a year, and I saw that one a few weeks ago, but this BCCH that appeared yesterday is the real deal for Leucism. #birding

Hubble observations of interstellar visitor 3I/ATLAS show that it looks like a comet. It has a teardrop-shaped cocoon of dust coming off a solid icy nucleus. The nucleus is roughly no wider than 3.5 miles (5.6 kilometers): go.nasa.gov/3UenJhD 🔭 🧪
