Fossil Shark Teeth ID Project

I am currently working on a shark teeth ID project. It is a personal project I am working on because I got gifted a multitude of fossil shark teeth of various species.

I am fairly sure that the teeth (seen in the two pictures below) belong to the family Lamnidae and are from the species Cosmopolitodus hastalis.

If these teeth are in fact the teeth of Cosmopolitodus hastalis they ought to date back to the Miocene and Pliocene (which are the two epochs of the Neogene). Although the species was still alive during the Pleistocene, fossils found of Cosmopolitodus hastalis in Cadzand (in the Netherlands) date back to the Miocene and Pliocene.

One of the shark teeth (the left picture below) gifted to me is so severely eroded that I cannot visually identify it, however it is still a gorgeous fossil.

Between the various shark teeth I also found what I suspect to be a part of a fossilised chela (claw/pincer of a crab) (seen in the right picture below). Considering the location of the find I think it might be from Carcinus maenas and could date back to the Pliocene.

Strandkrabben-Bisque

In der zweiten Julihälfte verbrachte ich Teile meines Sommerurlaubs auf der schönen niederländischen Insel Texel. Einer der Höhepunkte war übrigens das Treffen mit dem charmanten Krautjunker Goswin am Paal 17. Goswin kommentierte dieses Foto später damit, dass er darauf aussieht wie Bilbo, der gerade von Gandalf zu einem neuen Abenteuer überredet wird… In der Hafenstadt Oudeschild amüsierte ich…

Things I saw on my dive today

Anemone (no clue about the species, was brown)

Crabs, (Cancer pagurus and Carcinus maenas probably?? A few were swimming (small and orange), one was blue/black with red eyes)

Various brown/red small fish (I know basically nothing about fish so fuck knows lmao)

Sea squirts (on seaweed, clear with bluey tint)

Peacock worm (Sabella pavonina I'm pretty sure)

Sea star (Asterias rubens for sure, and larger bluey ones)

Urchins (Echinus esculentus ?)

Pipe fish (??? No idea lmao)

This is incredibly cool! It's a preprint so it's still undergoing peer review, but an enormous study on the terrestrialization of crabs over several stages and phylogenetic groups was just finished and there are some super illuminating findings for how crabs have evolved over hundreds of millions of years. Some of the most interesting implications are those of how invasives, like (my eternally beloathed) Hemigrapsus sanguinus and Carcinus maenas, often have the kind of traits for high habitat adaptability/tolerance that many of these common ancestors for terrestrial crab groups may have shared.

FULL TEXT check it out, it's a really awesome read!

Something from the Carcinus No Aliens AU

[daikatanaman]

Today was the day i finally started researching for science... i think.

I had to identify each species that my advisor managed to find on a beach.

They were collected in a beach which had rocks, on low tide, so some of the species collected were actually common from reefs.

I went from the crabs first, because I thought they were the easiest ones to identify... boy i was wrong, just the brachyura identification of the coast of brazil had basically 800 pages, but this big one here was actually easier to id, because, for one, because of the slippers on their backs, they are surely what the brazilians call a "siri", so from the family Portunidae, to get the actual genre and species was a little bit tricky, basically, the males from the genre Callinectes have their telson in a T form (the book is very vague about what the hell is a T, but its their telson), you had to see little spikes they have around the eyes to determine the species, its probably a Callinectes danae

its not their penice s btw,,,

these are pistol shrimps, one of them had eggs with them, i'll have to study some Alpheidae (pistol shrimp superfamily) identifications so i can ID these ones.

The other ones were 2 Carcinus maenas and a bunch of Clibanarius crabs, that i won't show cuz they're pretty gory, because they were stuck in their shells and i had nothing to break the shells, so i had to yank them out (worst part of doing ids with crustaceans).

also was a pain in the ass to look cleary throught the lenses of the macroscope, so i made a sketch based on what happened

thats it....

18.07.24 - Young Darwin Scholarship Day 4

The bulk of today was devoted to rocky shores. We went to East Prawle where we were going to lay quadrats and collect data on the species present at the various coastal zones but as the data software wasn’t working we just explored. I couldn’t take in much information because my pain has been getting worse, I’ve been getting more and more tired and it’s been harder to think clearly, so this post will mainly just be brief descriptions of some of the things I saw and photographed.

1-2. A male European Green Crab (Carcinus maenas)

3. A lot of different seaweeds. Important information is that they are not plants and some of them, such as red seaweed, parasitise each other which is interesting. I can’t remember which species it is but one of them has bulges that look like air sacks but are in fact filled with reproductive material (I guess semen would be the closest analogue). Others do have air sacks.

4. Some sponges of which I don’t know the species - genetically and evolutionarily the closest relative of humans that can be found in a rock pool.

5. Beaded Anemone (Actinia equina)

6. Snakelocks Anemone (Anemonia viridis)

7. The ornate underside of a Cushion Star (Culcita novaeguineae)

8. Rockpool Shrimp (Palaemon elegans)

9. A Grey Seal (Halichoerus grypus) observed from a distance (getting too close stresses seals significantly). This was an interesting find. We didn’t see seals when we were purposely seeking them out on yesterday’s boat trip but we saw one today and the Grey Seal, with it’s characteristic long snout, is more rare on our coastlines than the Common Seal.

10. An out-of-focus Glow-Worm (Lampyris noctiluca), curiously not a worm but a beetle. There were several in the verges between the beach and field centre after we returned from our final evening campfire. We also detected bats on our bat detectors and saw them flying around, possibly Daubenton’s (Myotis daubentonii) as a population nests by the bridge. We also took one last chance to try and spot otters. At one point in the gloom I saw some large ripples and what appeared to be a dark shape but I don’t know if my eyes were playing tricks on me.
