You're welcome! And thank you and Gayani for inviting me to join the project!! I love these sort of studies, combining so many skills to get at big cool questions like this.

Stephanie Baumgart, PhD 🦖🦆 @stephanopteryx.bsky.social · Aug 27

This was such a cool project to be a part of! I contributed scanning & rendering 3d anatomical models of some specimens, but this international team led by @gayani.bsky.social & @tdcapellini.bsky.social combined many methods to reveal how exactly humans evolved to walk upright on two legs. 🚶‍♀️🚶‍♂️

Say hello to Florida's newest established species, Typhlonectes natans - the Rio Cauca Caecilian! You can read about their relative abundance, distribution, & natural history, in our brand new paper:

journals.ku.edu/reptilesanda...

Here is one individual I CT scanned that had 7 babies inside!

A 3d rendering of a CT scan of a Rio Cauca caecilian with transparent body and bone colored skeleton, showing 7 baby caecilians inside, each rendered in a different color - counter-clockwise from tail to head - red, orange, yellow, green, light blue, dark blue, purple.

This budget proposal will make your life worse.

Call your elected officials and oppose it.

Joshua Weitz @joshuasweitz.bsky.social · May 31

How bad will it be? Catastrophic.

Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.

But, this is the WH's *proposed* budget.

Speak up now before it is too late.

(inflation adjusted $-s below)

NSF, NASA and NIH budgets per year, inflation adjusted from 2000-2025 along with the proposed cuts. NSF includes research component only. Massive cuts across all sectors, well below support spanning 25 years.

What can we learn about dinosaur physiology? 200 years after the 1st dino was named, new technologies yield amazing data from fossils. Physiology is vast, we hit on a few topics & gave ideas for improving hypotheses regarding how dino bodies may have worked. 🌡❤️🫁🦕🦖🧪⚒️🪶
