Fossil Preparation - First Extinct Dog! Hesperocyon skull and partial skeleton (30 million yrs ago)

So here's the complete time lapse fossil preparation video of one of the first ever known members of the dog family (Canidae) known as Hesperocyon. This fossil was found exposed on a private ranch in South Dakota and comes from the Brule Formation of the White River Group dating back to the Oligocene 30 million years ago. This time lapse condenses about 15 hours of prep time down to a couple of minutes. Below are a list of some of the tools I used for this prep project:
Hand tools (used for soft matrix only):
Exacto knife - for removing matrix close to the teeth
Pin Vice with Tungsten Carbide stylus - to clean between the teeth
Pnuematic air tools (linked to large air compressor):
Zoic Palaeotech ZPT Microraptor - Lower pressure air tool used for cleaning the Oreodont jaw and around the bones.
Consolidants:
3-4% Paraloid B72 & acetone - helps penetrate into the smallest of fractures to give the bone strength.

Girlfriend is a huge paleontology buff, she sends stuff like this to me all the time, and i always watch them all the way.
VERY beautiful fossil! Very satisfying seeing all that white stuff getting slowly chipped off the skeleton.

You draw really well!

[@Grendel1974]

Thank you 🙏. I am just learning this trade or skill. I have found a nice deposits close to me and have been teaching my self by just using different styles of brush and distilled water. videos like this really help!!

Thnks for sharing. I was wondering where it was fnd...oh i see in description!

Prepping teeth is difficult, but its always fun ;)
Recently I've prepped a Phytosaur teeth wich was a big challenge because the matrix was a lot harder than the teeth. But the teeth survived :D

Thank you for share about the liquid. I was wondering about that! Jaja

[@catholic3dod790]

Very interesting

[@Max-pj4ok]

Absolutely amazing work! How long did this take in total?

[@PalaeoArt]

Thanks Max. I reckon this one was about 12-15hrs in total. I've got to admit that I forgot to film the bulk of the preparation of main block as I had camera trouble.

[@Max-pj4ok]

@@PalaeoArt what it is incredible how long things like this really take. Videos never do justice as they are obviously shortened but it must take insane patience to do something like that.

[@DreadEnder]

@@PalaeoArt what only 12 - 15 hours!!! That’s insane!!! It usually takes me that long with a small ammonite

[@DreadEnder]

@@Max-pj4ok even 12 - 15 hours is insanely short! I was expecting at least 40 hours

[@nopenada8071]

So curious on the story on why these two were together. Possible bigger predator in the area at the time this one was scavenging? So many possibilities. Very cool.

Is the matrix bleached or is that just the lighting?

[@normblais5120]

Nice find. Was this a juvenile ? Its so small.

[@PalaeoArt]

Thanks Norm. This is actually an adult specimen. Hesperocyon wasn't very big as canids go.

[@Kamiis1STson]

where do you buy these things bro

[@user-nl6nd3fs7x]

hello please help me. if paraloid b72 in 30 gram, need how much acetone ? thankyou very much

[@chayan2397]

Great video how much is something like this worth

[@PalaeoArt]

Thanks very much. It's hard to say I'm afraid as although it an interesting association, it's not well articulated and both fairly common speices in that formation.

[@chayan2397]

@@PalaeoArt thank you for the reply I’m a new collector of fossils and looking to get something like this to be the central piece of my collection

Hesperocyon was the only dog species to keep its retractable claws with all other dog species now completely losing them
