A North American mammal skull
Good morning. In #deskDetritus today we have another North American mammal skull. Water rotted in northern Ontario🇨🇦. I lost the mandible in the process.

Jumping spider on a computer screen. Not an image of a spider, the live spider itself.
I have two jumping spiders that live in my #DeskDetritus. One visited the monitor during a rewriting session. I was able to get it to hunt the mouse cursor. Great writing break. 🧪

The #deskDetritus spans a long time temporally and intellectually. When the amazing @sbcrofts.bsky.social was doing her dissertation on crushing teeth I wondered if photoelasticty could tell us how cusps are loaded. The short answer is yes. But boy is it hard to interpret on shapes like this.

#deskDetritus Colombian edition. I am outside of Cali in a colleagues house. He collects weird seeds. I have no idea what these are.

My #DeskDetritus includes a couple of hummingbird nests I've found (on the ground).
Label is for the undergrad students that kept asking if it was marijuana.

You may wonder about my #DeskDetritus antecedents. How did I get here? This is from my mother's desk. A shed test from a Limulus (horseshoe crab).
My mom is an artist. Her detritus is better than mine.

A walrus penis bone sitting on a messy desk.
Here is an odd bit of #DeskDetritus. An unpaired bone from a walrus. The Os Baculum, or penis bone is called an oosik.

#Deskdetritus in this house features 17th-century delft tile, an errant fish skin (as those who know me won't be surprised), and coral

20cm 3D printed fish teeth.
I do think biologists have the best #DeskDetritus. Here are a couple of giant 3D printed fish teeth from @karlycohen.bsky.social work on homodonty.

Maybe the oldest #DeskDetritus is this 3D printed cross section of a cownose ray jaw. It shows the mineralized trabeculae that formed the basis of my PhD. I found these struts about 18 months before I defended, so they became my dissertation.

The latest episode of #DeskDetritus is a 3D printout in gray PETG of a new species of blenny with a lovely little topknot -Acanthemblemaria aceroi. I print a skull of each little fish I have helped to describe - handy since none have been longer than 25mm total length.

One of my older pieces of #DeskDetritus is this 3d print of the head of Belator an armored gurnard. I have added an eye that blinks because it entertains me.
This dates to when @adafruit.com sold subscription boxes with cool weird electronics.

Three teeth from a six gill shark.
Here is an oddball #DeskDetritus. @kacorn.bsky.social's paper on Jawzall, a tool for measuring dynamic function of shark teeth, used teeth from a six gill that stranded near the labs. A few are still on my desk. Including the symphysial.

A return to #DeskDetritus. This clay sculpture by @fernandaoyarzun.bsky.social has the DNA sequence of the fish that modeled for the sculpture.

And now I no longer need any streaming services. #DeskDetritus is all I need. Fascinating.

The skull of a nine banded armadillo, dermal armor still intact.
Here’s the skull of one of the nine banded armadillos that provided tissue for my dissertation, still hanging out in my office 27 year later. #DeskDetritus

My favorite piece of #deskdetritus is definitely the puffin I picked up on our honeymoon—maybe not a shorebird, but certainly cute!

My hand holding a large cone snail shell in front of my desk. It’s very worn, mostly white with a pattern of dark brown bars.
My hand holding a clear plastic wafer carrier. Inside is a silicon chip with a dark indigo-blue coating and rows of oblong silver areas
Here’s a couple of my current bits of #DeskDetritus - a very large cone shell and an old Zyomyx microarray chip.

Today's #DeskDetritus is a poacher, an armored fish, and a 3D printed section of the armor. We are
Interested in the

Knitted clingfish.
I have spent 20 years messing around with clingfish. I love them. Dr. Molly Grear, an engineer and knitter, made me this yarn clinger complete with fins and disk. She also knits female scientists.

Skin of a large Burmese python held up by 9 scientists.
Large Burmese python held up by 7 scientists.
In today's #DeskDetritus entry two pictures of the same snake 5 years apart. The 18 foot Burmese python belonged to Al Richmond. Beth Brainerd, my PhD advisor, and a bunch of her students and in the later image many of us have graduated and the snake is now a tanned hide.

A fish skeleton mounted on white paper.
In this installment of #DeskDetritus a skeleton that was used to bait a lander trap in the Atacama Trench. This went to 7800m and lured in isopods and other hadal inverts. Given to me by Mackenzie Gerringer.

Baleen from a minke whale.
Entry 2 in the #DeskDetritus pile is on the shelf next to my desk. A sample of baleen from a minke whale. Used in @cmdonatelli.bsky.social @fishbiomeganist.bsky.social and Shirel Kahane-Rapport's bioinspired filtration work.
