Sue update

by Greg Mayer She’s gone. I was at the Field Museum on Wednesday for the first time since the previous month, and the removal of Sue the Tyrannosaurus rex has been completed. Viewed from the balcony above, visitors walk through Stanley Field Hall, seemingly unaware of the ghostly white outline of Sue’s now departed plinth. […]

So long, Sue…. see you upstairs!

by Greg Mayer Sue, the iconic Tyrannosaurus rex that has inhabited the Field Museum of Natural History‘s Stanley Field Hall since 2000, is coming down. But, shortly after she comes down, she’ll be going up– upstairs that is.  The Museum announced plans last year to replace Sue in Stanley Field Hall with a model of […]

Here’s the organism (well, sort of. . . .)!

Did you guess what organism made the pattern below, found on a recent dive around the hydrothermal vents off Tonga? Here’s the answer in the second tweet: For comparison here is a live "Paleodictyon" from the Mid Atlantic Ridge. Pic from Paper by Rona et al. #UnderwaterFire Tonga — Polychaeta Species (@WPolyDb) December […]

Identify the organism that made this pattern

Here’s a new tweet that Matthew sent, showing a pattern found underwater by ROV SuBastian dive #96 (dive #97 starts at 11 a.m. Chicago time, and you can watch it here).  These dives are sponsored by the Schmidt Ocean Institute, and are currently investigating hydrothermal vents around Tonga in the Pacific. Oh wow, one of […]

Readers’ wildlife photos

Reader Mark Sturtevant sent some diverse photos from his Ikea Cabinet of Mystery. About a year ago I had posted pictures showing a few specimens from my “Cabinet of Mystery” (from Ikea!). It is once again time open its glass paneled doors and peer inside for more oddities and curiosities. We begin with a fossil […]

A ten pound frog frog lived in ancient Madagascar

A frog that could swallow a small theropod dinosaur? Well, maybe: it was large enough, and weighed in at a hefty ten pounds (4.5 kilograms). This animal, with the clever name of Beelzebufo, was first described in 2008, but a new paper in PNAS by Susan Evans et al. (reference and free link below), describes […]

Giant “paleoburrows” dug by extinct mammals

In the last few years, geologists have been finding—mostly in Brazil—large “paleoburrows” that were almost certainly dug by large, extinct mammals such as giant ground sloths. These burrows can be up to 3000 feet long (!) and 5 feet wide, though the very long ones were surely dug by many individuals over many generations. The […]

Readers’ wildlife photos

Please keep your photos coming in; I have a decent backlog, but you know how I worry. . . Today we have some photos of fossilized wildlife, all taken by reader Mark Sturtevant. His notes are indented. As a change from the usual stuff that I have been submitting, I thought to share pictures of some specimens […]

Happy Thanksgiving (and a fossil turducken)

Today’s Bloom County cartoon, courtesy of reader Stash Krod (click to enlarge): Reader John W. sent this salacious Thanksgiving cartoon (if you don’t know what a “turducken” is, go here): And, for some biology on this day, we have an item reported in September by Discover Magazine and National Geographic: a “preshistoric turducken”.  Yes, it’s a […]

Earliest organisms: 3.7 billion years old?

There’s a new paper in Nature that has everyone excited, for it reports what is said to be the earliest evidence for microbial life—”microbial structures” dated 3.7 billion years ago. The paper, by Allen P. Nutman et al. (reference and free link at bottom), describes what are said to be ancient traces of stromatolites—layered colonies of cyanobacteria that trap sediments […]
