Palaeontologist and Postdoc @LivEvoBiomech | Evolutionary biomechanics of birds 🦆 and dinosaurs 🦖

[Samuel Cross @SamRRCross]

Our new paper is out in @CommsBio! We investigate body shape, limb & trunk kinematics, and energetic costs in different duck breeds, testing to see whether there are clear mechanistic links between them (i.e. does form -> function)

Short story is...Its complicated!

[Communications Biology @CommsBio]

🦆🐾Duck breeds selectively bred for disparate body shapes are found to walk with different limb kinematics but incur similar energetic costs. This is attributed to the interplay of dynamic kinematic and modular anatomical processes.

Hey all! I have a new portfolio website.

This will be the main hub for my images going forward.

It would mean a lot to me if you shared this around: https://t.co/Ecix4UTkRW

Most birds use a funny running style: grounded running. It's a paradox: GR costs more energy than normal running, but animals usually minimize costs.

Do birds waste energy? We resolve this with a model of the emu (the best bird).

Hopefully of interest to anyone working on #bird & #theropod locomotion.

Should have a proper🧵up soon!

@Sketchy_raptor Congrats Matt!! [P.S. Champagne credits go to Karl😉]

Check out this cracking @preLights post by @LivEvoBiomech @SamRRCross & @james_charles90 featuring Lauren Thornton @TaylorJMDick @JohnRHutchinson @GlenLichtwark @McGowanBiomech @cclemente4 & co's recent @biorxivpreprint unlocking the secrets of kangaroo locomotor energetics

[preLights @preLights]

Should we all be hopping like a kangaroo? 🦘

@LivEvoBiomech , @SamRRCross and @james_charles90 review an exciting #preprint unlocking the secrets of kangaroo locomotor energetics. Work from @cclemente4 and colleagues.

Take a look at the #preLight ⬇️ 👀https://t.co/Qs6LBMKeGz

Bird & Dinosaur Biomechanics @YorkshireNHM this Saturday - talking about the 'hows' and 'whys' of biomechanical modelling in the fossil record, with some classic (dino) examples and my own stuff on birds

[Natural Sciences Museum @NSM_UK]

Visit the YNHM this Saturday at 2pm to explore the biomechanics of dinosaurs.

Presented by @SamRRCross, PhD Student at the University of Liverpool.

@Sketchy_raptor Exquisite.

[Samuel Cross @SamRRCross]

@lordpyron98 @ProgPal2023 @Sketchy_raptor @apwoodbailey Thrilled to hear you’ve enjoyed the conference Piero! And congrats as well on a great poster!

[Samuel Cross @SamRRCross]

@HoudzGeorge @apwoodbailey @Sketchy_raptor Thanks Hady!! Been a pleasure to host, and congrats on an excellent talk!

[Samuel Cross @SamRRCross]

@Sketchy_raptor @apwoodbailey Hard agree with that one! Had a fab time hosting with you and @apwoodbailey, and thoroughly enjoyed hearing about the outstanding science our delegates presented!

[Dr Matt Dempsey @Sketchy_raptor]

Co-chairing ProgPal '23 with @SamRRCross & @apwoodbailey has been one of the highlights of my career. I can't imagine a better team. And we've had a great time meeting all the attendees and learning about their research. It's my final ProgPal, so I'm a bit emotional this evening!

That's right friends, I am the keynote speaker for #ProgPal2023! I'm so excited to share my current work quantifying mammal locomotor repertoires! 🦥🦘🫏🦇🦦
See you all there!

Final few hours to get your registrations in!

[Samuel Cross @SamRRCross]

Last day to register for ProgPal 2023!

[Progressive Palaeontology 2023 @ProgPal2023]

While we're no longer accepting abstracts, there's still time to register to attend ProgPal 2023. For postgrads working in palaeo, this is a prime opportunity to meet your peers, share research stories, and have an all-round great time.

Registration closes 23:59 BST, 25th April.

[Progressive Palaeontology 2023 @ProgPal2023]
