I have a soft spot for the palaeontologists who originally stuck the iguanodon’s thumb on its nose.

...& I’m a bit skepticism of how skinny our modern vision is.

Ahh, this makes more sense! Spindly terrestrial dinos confuse me given the chonkiness of modern critters.

And gets at how complicated it is to figure out current-extremely-temporary consensus of fossil reconstructions.
PSA: Palaeontologist & evolutionary biologist @paleoblais is tackling questions in the replies.

(I love my scicomm kin jumping in when I’m out of my depth! 💙🦕☠️)

Fort Cronkhite, California is one of my fav beaches.

Every beach has many geologic processes are just waiting for you to notice them, but Cronkhite takes you on a geologic tour of the Bay Area. Looking over rocks to surging wavesLooking down a shallow pebble-sand beach with surging waves, bluffs in the distant background
Here’s the cliff bluff of the beach, my Earth Ring (with or without hand) for scale.

Can you see thebeds, layered lines of rock deposited at the same same? See the pebbles?
Those cliffs erode, relinquishing their pebbles on to the beach.

The pebbles were originally from all over the ancient Bay Area, giving us a hand-sized geologic sample of the region.

Once upon a time, an underwater landslide (turbidity current) buried this particular patch of sea floor.

The landslide deposits (turbidite) is that tall yellow sandy bit.
Turbidity currents are an interesting style of landslide because they’re density-driven flows: a dense fluid (water & sediment) running out under a less-dense fluid (seawater) across solid ground.

They can be fast or slow.

Stratigraphy is how geoscientists learn the order of events for a landscape. I always think of it like unravelling a murder mystery where your crime scene is rock.

It only has 6 rules, but you won’t need all of them to read these particular rocks.

I’m still thinking about these fantastic feet (tip via @RallidaeRule)

And while yes, they are indisputably the Best Bird Feet, I’m still feeling strongly that’s a split title with at least a dozen species.
Blue-footed boobies know their feet are spectacular, featuring them in an “Look at mah sexxxy feet!” dance.

Aside: did you know other species of boobies are also adorbs?!
Have you seen snowy owl feet? They’re fluffballs of doom. Like kittens? You’ll love this cozy nest of feathers encompassing freaking terrifying death-talons

Our latest #infographic for the @UofAALES #EMEND project is here! Check out the full infographic here (ow.ly/hjQs30nknje) or read more below! #scicomm #sciart @NSERC_CRSNG @EllenMac_UofA @charlesnock (1/8)
First of all, what is EMEND? This is a @NSERC_CRSNG funded experimental harvest area where researchers are able to study the effects of retention #harvest strategies on biodiversity, soil properties + more. (2/8)
'Retention harvest' means keeping some trees either individually or as patches after harvest. This might help improve #conservation of #biodiversity within the area & can be used to mimic natural disturbance patterns. (3/8)

#Khashoggi Case Thread: I am going to ‘pin’ this post to use it as an ‘Info Thread’ on the #Khashoggi Case. I am in #Turkey. I’ve been following the case closely and with access to sources & experts here. This is a very ‘sensitive’ criminal case due to ‘Diplomatic Booby Traps’!!!
The Evidence Obtained Outside Cameras will not show any evidence of ‘tempering’ but other than license plates of dozens of diplomatic cars (Many with tinted windows-large trunks) with related time stamp, drivers Info, model/year: Nothing.
#Turkish Intel-Investigative Bodies also have the list of all Diplomatic & Private Saudi & “other significant’ Planes in #Turkey for the period of ‘interest.’ Many of the Target airports have their own security cameras & related evidence.

It's art up for review in opinions, of course I'm going to gravitate towards something shared with interest, when he didn't say a word for 2 days! Why was he there? #opendata #smartcities #bigdata #ai
I went through every single video he released in hip hop to understand him not saying a word. Easy to work out, he's a very bitter man who has absorbed all his parents immigrant opinions at home #opendata #smartcities #bigdata #ai
His parents are not middle class anywhere & neither is he #opendata #smartcities #bigdata #ai
