yoyoyo! not very often does this rascal get da chance to covah somethin that is mo o less a current event! Well today must be Not Very Often then! Above is a rapscallion known as entelognathus primordialis. His name translate to Primordial Complete Jaw and he is so impress’ because he is the first known fish/animal/organism to have a (somewhat [lol]) recognizable face. Befo him there were just feesh and shit with eyes and noses but they looked alien yo.
Their jaw is also pretti importante! It was fully formed and honestly somewhat resembles many many organisms today (including humans). Without this link in da evolutionary chain, we may all end up being ugly like eels and hagfishes (REAL ugly, not e’en tryna front)
Anyways, Entelognathus was a placoderm. Placoderms were the armored fishes that lived mainly during the Devonian. In case you have forgotten, Dunkleosteus (huge rascal) was a placoderm!
check out day strong, defined, masculine jaw! ^ I wondah who he got dat from…? hmm.??
yo yo yo! sorry bout da hiatus but when the goin gets tuff, the tuff get off tumblr fo a little while. Anywayz, im back and with me is this lil rascal, Vancleavea Campi. These guys were non-archosaurian archisauriforms, which besides soundin like it dont make no sense, what I gather from it is dat these were very early ancestors of what today is now crocodiles and certain birds. Vancleavea never got too big, averagin about 1.2 m (ruffly 4 ft) and lived during the late Triassic.
However, these lil rascals were a bit different. They differed from otha archosauriforms and tetrapods in that they tails had scale like things (called osteoderms) extending from them rather than tall neural spines. Their long fin like tail and their short limbs suggest they were semiaquatic lil ragamuffins, but I’d lean more to the aquatic side just because look at those arms…. tiny (do some curls or some’in).
Here we see Vancleavea on the long (& endless) quest fo some booty. maybe if he lifted things wuld b different. But alas, Vancleavea searches on, hopelessly…
If tha 1rst thing that came to yo mind was butterfly turtle, then we in the same goddamn boat. This was Henodus and he was an odd lil rascal. He may look quite like a lil turt-turt, but there were some anatomical differences as well yo. Turtles got limbs situated inside their ribcage where this rascal had normally positioned limbs (not that you can tell cuz of his funky lil shell).
Even with his “normal” limbs doe, they were apparently pretty weak (doesnt even lift) and suggested lil Heno spent little to no time on land. The water called to lil Heno and he answered. Although Henodus is a placodont (marine reptiles usually not very large) he seems to be an exception cuz he lived more in brackish (salty-fresh water) or fre$hwater lagoons rather than tha big open sea.
Anyways, Henodus lived in the waters of the Late Triassic. Being a placodont, he usually never got bigga than a meter long (tree feet). Besides that strange lil rascal on his back tho, another funfact characteristic was that he only had 2 teeth! One on each side and a beak in da middle.
Not much tops da Henodus in terms of strange water dinosaurs. He was a swimming bloq if yu aks me.
If this pic looks famfam, its cuz its me yo! Naw, its just my icon cuz there a special place in my <3 for the Basilosaurus. My first post was akshully devoted to this rascal, but I figya’d I ought to go mo in depth. Anyway, dont let the “saurus” part of his name trick you. He aint a reptile at all but instead a whale! When yu think prehistoric whale, Basilosaurus needa come to yo mind. Due to his misleading name tho, other scientists wanted to rename him Zeuglodon to portray his mammal side. However, once a name is given, that name sticks (lyk a misleading super glue of false).
Big ol Basilo roamed && ruled the seas of the late Eocene. They grew up to 18 meters (60 ft) and had quite different anatomies compared to modern whales. Basilo wasn’t quite suited for deep swimm’N and his movement apparently looked strange (based on his muskles yo). fun fact!: my boy H.Melville has a few ch. devoted to these bois. Either way tho, he was a bad bxtch and holds much respect from this simple water-dino enthusiast.
Whale, whale, whale, what do we have here? Big, beautiful Basilo baby makin
HOLD THA GODDAMN FONE! ok, you can hang up, but then pay attention plz. After doin a lil more research on the Megalodon, I have found some craZ new info out. Remember way back when I mentioned tha ancient sperm whale Leviathan Melvillei? Well I said that Melvillei and Megalodon were the badazz M’s that ruled the seas of the Miocene.
Well one thang that was different about Leviathan Melvillei and his descendant Physeter Macrocephalus (sperm whale) was the teeth. Sperm whales feed with more suction force while Melvillei had functional teeth that could chomp ChomP CHOMP! This makin me think that Megalodon and Melvillei bein the top dawgs were competing for tha same limited food source. Only 001 dawg can be true king of the sea and im thinkin thats Megalodon. Melvillei had to dive deeper and develop different things to feed on (squid) which required different ways of feeding. This is why sperm whales IZ the way they iz (possibly).
Megalodon affected how different species functioned and evolved. This has been an epiphany. Peace out yo.
"AWWWWWWWWWWWWW YEEEEEEEEEAAAAAAAAAHHHHH" - ^ that megalodon tellin toothed whales ta suck it
I'm so glad j can across your blog!! I love learning about water dinosaurs. Think you could do more on the megalodon?
absahlutely lil mama
GET OVER HERE! This was my boy Jaekelopterus Rhenaniae and he a sea scorpion. Yez, if you thot scorpions only lived in the desert o under rox, yu was wrong. Even though we call em Sea Scorps (Eurypterida), it is speculated that they also lived in fre$hwater and streams, lakes, etc. yo.
These arthropods were one of the biggest ever to inhabit the earth, ranging up to 2.5 meters (8.2 feet). Imagine a bug that bigger than you and got lil claws. If that dont make yo head flip nothing will. Luckily, these sea scorps lived way back in the Devonian (remember with Dunkleosteus the big armor head fish) so the chances of running into em again is pretty slim…
Plz focus yo attention to Leedsichtys, the giant ass fish. Leedsichtys was a pachycormid (prehistoric bony fish) that lived in the seas of the Mid Jurassic. These fish were among the largest to eva inhabit our lil ball of water and rock, but exactly how big is subject to debate. Unfortunately the fossils of these gentle giants may be pretty plentiful, but they are almost all incomplete or missing something. Some scientists say they are round 9 meters, while others be claiming they around 16. Either way, they some big ass fish.
However, like some big fish of our time (whale shark, basking shark, etc.) these guys were filter feeders and mainly ate zooplankton. One thing thats fo certain tho is that Leedsichtys were champs. They had few predators and some fossils show Liopleurodon sized bite marks, but with signs of healing. So some big pliosaur took a bite, and Leedsichtys was just like bitch plz heres my tail. Tail says smack.
Plz contain yo excitement, because yez, the pic above is in fact of an (semi) aquatic sloth. Thalassocnus was his name, and swim swim swimming was his game. Honestly, not too much is known about these lil rascals, but apparently they grazed on seaweed and sea grasses. Like some semiaquatic air breathers today, these guys used they claws to anchor themselves to the bottom while they chawed.
They lived on the coast of South America (Peru) in the Miocene and Pliocene. Unlike their descendants, these sloths had ambition. Apparently fossils show that they eventually moved from the safe shallow waters to much deeper waters. Deeper waters, bigger predators yo. Sea sloth Thalassocnus dont give a shit.
