This gorgeous trace, one of ‘Dolf Seilacher’s favourite genera, is Paleodictyon from the Basque Coast 🇪🇸 taken by Dr. Mángano. It’s a prime example of the problems faced historically in ichnotaxonomy. ▫️
I know, I know. Taxonomy?! But ichnotaxonomy is actually an incredibly creative solution to a decades long problem.
▫️
Biologists classify based on the phylogeny (the evolutionary history) of the organism. Ichnologists.. well, we very rarely know the organism that made the trace! For example, after years of searching, we still don’t know the creator of Paleodictyon 🕵️‍♀️. Because of this, it’s often impossible to place ichnotaxa within a biotaxonomic scheme. So, after decades of frustration 😤, they made their own system! #rebels
▫️
I like to think of the difference like this: Where phylogeny is the governing principle in biotaxonomy, behaviour is the governing principle in ichnotaxonomy.
▫️
Of course, the interpreted behaviour of a trace maker is just that— an interpretation. It can change with time. The one thing that won’t change through the decades is the shape of the trace fossil. We know from several seminal pieces of work (hello, Seilacher!) that the shape of a trace fossil is often closely related to behaviour. ▫️
Ichnologists decided that they would use the shape of a trace fossil, as a reflection of the trace makers behaviour, to classify them. They use some distinctive yet variable trace fossil features, called ichnotaxobases, to classify.
Stay tuned for different examples of ichnotaxobases, and for more of that #tracefossilgospel ▫️

The crater chain called Cantena Davy, as seen by #apollo12.

Seen here are 23 small, similarly sized craters formed in a line! What caused this crater chain?

The most plausible scenario for the formation of the crater chain is impact by a #comet or an #asteroid. Comets and asteroid are weakly held together by their minuscule gravity, and can be ripped apart by the tidal forces of a larger body (Roche limit). So, a comet or an asteroid on its way to impact the #Moon got fragmented by the Moon’s tidal forces. Each of those fragmented pieces hit the surface at slightly different times, due to the rotation of Moon.

The Moon is known to have many crater chains, called Catenas. Although, not all catenas are formed by the same mechanism as above. Some are formed due to volcanic activity and some due to secondary cratering.

A Catena Davy like crater chain has also been found by the Galileo spacecraft on #Jupiter’s moon #Ganymede. In fact, Jupiter was key to understanding how these types of crater chains form. When the comet Shoemaker-Levy 9 got fragmented under the massive tidal forces of massive Jupiter and impacted it, we realized how crater chains on surface bodies must form.

Amazing how something that happens on Jupiter can teach you about what happened to a feature on the Moon! Science.

You know the biggest oilfield in the world? Yup, the Ghawar field in Saudi Arabia.

If you could get an exclusive access to see what the reservoir looked like. The view won't be far away from this one. Heavily fractured everywhere.

The more fractures, the more pathways for oil and gas to flow to the producing well.

Some reservoirs are not that lucky and trap the hydrocarbon tightly. This is why we make use of hydraulic fracturing, to try to create more pathways to ease flow.

What kind of reservoir have you worked on?

Remembering one of my favorite minerals to have passed through my collection, a 265 carat double terminated facet grade Aquamarine gem crystal from the shigar mine in Pakistan. Internally flawless throughout the majority of the crystal, this prism catches and reflects even the slightest amount of ambient lighting. The crystal can be read through with ease. It is an exceptional example of the top quality aquamarine crystals produced by this well known middle eastern mine. It was sold years ago and is in a friend's personal collection.
