I LIKE TURTLES!

@calebwieszczyk8247 Am I not Turtley enough for the Turtle Club?

Me to, I have one....well a tortoise, but close enough

I agree, they taste great!

Lol me too

[@calebsmith2362]

I can appreciate the manner in which she casually presents the ichthyosaur plush to the viewer at 6:46. Don't stop 'til you reach the top!

[@Cryptic_Bigfoot]

The way the ichthyosaur moved around was utterly hysterical! Also as always the show is great for keeping up with science news.

[@blackbaron0]

I agree. Good to have a bit of light heartedness.

[@colonelklink2164]

That Ichthyosaur plushie…

[@BenGThomas]

It's a plushie from the London Natural History Museum! I love it so much!!

[@DGFTardin]

7:09 She is slowly giving in to Doug madness!

[@user-gv4by8tv6l]

Not so slowly.

[@Katzztar]

Both she and the plushy deserves a thumbs up.

[@a787fxr]

@8:40 "we're going with that" !:- ) Sounded good to me

[@DinoNico95]

I like how Ben was excited lol

[@Saiku]

I want to live in a world where turtles the size of cows just walk around doing their thing. Everyone likes turtles.

Me too. The Great Atuin moves!

[@catherinehubbard1167]

Loved this report! The roving, acrobatic ichthyosaur stuffie was a hilarious touch. I bet I know what ichthyosaur-obsessed individual it belongs to.

[@enormousderek]

I love watching Emilia have to pronounce difficult names.

[@timopoling6447]

I feel that everyone should have their own shoulder Ichthy ❤

[@The_PokeSaurus]

Man, Mars having an effect on our oceans makes you realize the whole solar system is connected.

[@leechild4655]

really. like jupiter is the bouncer at the front door so mars is what, hall monitor?

[@The_PokeSaurus]

@@leechild4655 I thought the same!

[@bartroberts1514]

Really, Mars isn't having a discernable effect. The paper either misunderstood the Myr Cycle, or more likely the editors were sloppy about removing the ambiguous phrasing in the paper. Mars is ~6.2 * 10^23 kg in mass, and keeps a distance of about 225 * 10^9 m away from Earth. By the inverse square law, Mars has about the same effect on Earth as a smallish orca swimming in the ocean. And there are a lot of orca, and larger, things in the seas. Elephants on land, too. Dinosaurs, as well. Any actual impact of Mars would be lost in the noise. It is likely the results are connected to Myr in some non-Marsy way. Though yes, solar system is connected. But Jupiter? So much farther away, so much less influence. People who make these aphysical astronomical planetary claims are very bad at math and science.

[@tobiasware]

Astrology rules! This is scientificul-like evidentiary stuff this is! Nostrodamus was a prophet! Ok, I can't keep going with a straight face.

[@jamesmitchell6925]

It makes me think about how empty space is. If each little ball of rock/stuff is swaths of space apart but still effecting each other, I can see how planets are moving things around here…

[@jamesolivier5224]

Brilliantly done. It's clear that you've become more comfortable and confident as a presenter. You are now the new favorite. I adore the cheeky fun too.

[@brianedwards7142]

Speaking of river turtles, there was news here in Australia that an echidna was caught in the act and filmed raiding the nest of a critically endangered white-throated snapping turtle (Elseya albagula) and eating the eggs. This is a first ever reporting of an echidna eating anything except insects (ants and termites specifically) but could explain the decline of the turtles.

[@thinking_toomuch]

OMG that ichthyosaur is wild! It won't stay still🤣

[@capt.bart.roberts4975]

That was one hell of a fascinator!

[@bmortlock1956]

I simply LOVE Emilia!!! She is that "Quiet Funny" & loves picking at Doug !!! Her poise & presence is delightful. 😊👍❤🎯

[@ihcfn]

Adorable.

[@YusufGinnah]

Babe, wake up! New turtle doccie just dropped.

[@matbroomfield]

I'll always have a soft spot for the two original presenters on this channel, but this young lady is a lovely addition to the core team.

[@uhadonejob]

My new favourite pronunciation of the word turtle.

[@madmonkey6621]

pervert

[@DisorderedArray]

@@uhadonejob What was your old favourite? ...Twerdal?

[@John.0z]

Snorkelling on a reef is all you need to know about the noise. It is indeed surprisingly noisy. The wash of the waves is a minor part of that noise. Now I am waiting for a fossil turtle to be named A'Tuin! (preceding that with "Great" might be asking too much) To properly fit Terry Pratchett's description, it would be only proper for this to be a very large species. You are getting better and better at the presentation task Emelia. 🙂

[@T4N7]

I normally just come here to learn, I was not expecting to laugh my ass off 😹😹😹😹

[@jonwashburn7999]

Imagine having Emilia as a professor. Fun learning.

[@loganlogon3720]

And in a surprising new paper released this week recent photographic evidence shows that Icthyosaurs may have enjoyed planking on peoples heads....

[@aussiesam01]

Well done for keeping a straight face through all that!

[@persianking44]

The fact that Mars is able to influence Earth's deep sea ocean currents has some fascinating implications, and I can't wait to see what answers (and questions) more research about it will yield. But even more than that, I think it also has some inherent implications regarding life on other planets, or at the very least how other planets might influence the climate on planets where life is present.

[@Leptospirosi]

This whole ophtalmosaurus thing escalated quickly!

[@velutumbra]

"Stupid Flanders", if Homer was reading it.

Finally the Jurassic period is revealing some new animals

It's Emilia time this week! 🎉🤟✌️💪

Stupendemys is now a close second favorite prehistoric creature for me. My soul animal and beloved tort.

[@CalebJMartin]

5:35 - Stupendemys sounds like someone artificially lengthening 'stupendous' for comical effect 😂😂

My, what a jolly good ichthyosaur you have there. How stunning! It gets my like.

Can I suggest a special episode dedicated to funny taxonomic names? We all will have fun 😂 Thanks for sharing!

[@kyrab7914]

I love that tho y'all are professional and all, this medium also allows for a vagrant ichthyosaur plushie. And much more

Love everything and everyone on this channel! That stuffed Ikybengeeosaur needs a turn presenting news, and perhaps a naming contest! It sure had fun, and likely was pining for Ben (and the fjords).

[@loriblain3266]

Wonderful to hear some good news about coral reefs.

[@aussiesam01]

Follow the information from Prof Peter Ridd. He was sacked from J Cook Uni to shut him up. Australian coral reefs are doing very well.

I love you guys, this channel's just awesome. Always enjoyable and interesting

[@littleoldlady523]

Emilia, you are really getting good at this: I look forward to the day you're anchoring at the Beeb.

[@Briteiis]

Subscribed, and the first thing I did was to look over the first few dozen or so episodes. I hovered over them to get some idea of which ones featured this presenter and clicked the _"Watch Later"_ symbol. I'll probably watch some of the others as well, however, in keeping with my _"Watch that which is both informative and pleasing"_ policy, those will be first. If I discover more as I go, it may be some time before I watch the others.

[@tolbaszy8067]

Led Zeppelin's "Stairway to Heaven" would be my choice for coral reef regeneration. Emilia is brilliant! Thanks for superb commentary!

[@mrfelface]

props to her how she is able to keep on going while the plushy climbs all over her

[@Titus-as-the-Roman]

Has anyone ever seen an Alligator Snapping Turtle, or even just a really big Common Snapping Turtles, Had a few run ins and it's always exciting. In person you'd swear it was a dinosaur of some kind, they're so big and Mean looking that newbies might not think they're real When folks see Hummingbirds live for the first time they're always astounded and think their not birds.
