Hello, i have an ask from the pics. Are these an Crinoid stem ?

These are little ones from the kids activity to dig and search sets from those Dinosaur parks / museum bags. Likely all shells & sponge right?

Hi! :D

So I'm gonna start by saying, I am most definitely an amateur, haha, so my word is not 100% certain, but,, I think I may have some news for you!

The segments in those pieces do resemble some Crinoid stems and columnals I've seen, but I've never seen a stem that varies in diameter like those. Yeah, it could be erosion, but the fact that it is all of them, the same precise, cone shape is a little suspicious!

But guess what else is segmented! Nautiloid shells! and guess who evolved straight shells quite a few times! Nautilods!! I believe what those are is Orthocones! (straight, long, shells of Nautiloid Cephalopods) (a squid-like animal, with a shell) They were around from late Cambrian to the late Triassic:) And in size, they range from less than 25 millimeters to over 5 meters!

Here is an example of an Orthocone!

looks pretty similar to yours, do you think?

That is so awesome, friend! Yeah, Crinoids are awesome too, but you definitely do have some of those in that polished egg (It's so pretty)

Also check out this huge one!

also yeah, the stuff from the museums and kits looks like shells and sponges to me, but again, im not a professional :) and I mostly know brachiopods haha

Thanks for showing me your cool fossils! They are lovely, I can imagine that joy you felt when you found them! Isn't fossil hunting the best thing ever!?! :) You're blog is inspiring me so post more of my fossils!

Oh, and if you want, give your Orthocones a little kiss for me! (I love to give my fossils a little peck, pretty cool to be able to kiss something that's millions of years old, right?)

Ammonites were some of the most diverse organisms in the ancient ocean. The Museum holds one of the world’s largest collections of ammonites, containing nearly two million specimens that represent 300 million years of Earth’s history!

Наутилус (лат. Nautilus) — род головоногих моллюсков, которых относят к «живым ископаемым». Самый распространенный вид — Nautilus pompilius. Наутилусы относятся к единственному современному роду подкласса наутилоидей. Первые представители наутилоидей появились в кембрии, а его развитие пришлось на палеозой. Наутилиды почти вымерли на границе триаса и юры, но все же дожили до наших дней, в отличие от своих родственников аммонитов. Некоторые виды древних наутилусов достигали размера в 3,5 м. Представители самого крупного вида современных наутилусов достигают максимального размера в 25 см.

Спиральный «домик» моллюска состоит из 38 камер и «построен» по сложному математическому принципу (закон логарифмической прогрессии). Все камеры, кроме последней и самой большой, где разме��ается тело наутилуса с девятью десятками «ног», соединяются через отверстия между собой сифоном.  Раковина наутилуса двухслойная: верхний (наружный) слой – фарфоровидный – действительно напоминает хрупкий фарфор, а внутренний, с перламутровым блеском – перламутровый. «Домик» наутилуса растет вместе с хозяином, который перемещается по мере роста раковины в камеру попросторней. Пустое жилище моллюска после его гибели можно встретить далеко от его места обитания – после гибели «хозяина» их раковины остаются на плаву и перемещаются по воле волн, ветров и течений.

Интересно, что двигается наутилус «в слепую», задом наперед, не видя и не представляя препятствий, которые могут оказаться на его пути.И еще одно удивительное качество этих древних обитателей Земли – у них потрясающая регенерация: буквально через несколько часов раны на их телах затягиваются, а в случае потери щупальца быстро отрастает новое.

Nautilus is a genus of cephalopods, which are classified as "living fossils". The most common species is Nautilus pompilius. Nautilus belong to the only modern genus of the Nautiloid subclass. The first representatives of the Nautiloids appeared in the Cambrian, and its development took place during the Paleozoic. The Nautilids almost died out on the border of the Triassic and Jurassic, but still survived to the present day, unlike their Ammonite relatives. Some species of ancient Nautilus reached a size of 3.5 m. Representatives of the largest species of modern nautilus reach a maximum size of 25 cm.

The spiral "house" of the mollusk consists of 38 chambers and is "built" according to a complex mathematical principle (the law of logarithmic progression). All chambers, except the last and largest, where the nautilus body with nine dozen "legs" is located, are connected through holes with a siphon. The nautilus shell is two–layered: the upper (outer) layer – porcelain–like - really resembles fragile porcelain, and the inner, with a mother-of-pearl luster - mother-of-pearl. The nautilus's "house" grows with its owner, who moves as the shell grows into a larger chamber. The empty dwelling of a mollusk after its death can be found far from its habitat – after the death of the "owner", their shells remain afloat and move at the will of waves, winds and currents.

Interestingly, the Nautilus moves "blindly", backwards, without seeing or imagining the obstacles that may be in its path.And another amazing quality of these ancient inhabitants of the Earth is that they have amazing regeneration: in just a few hours, the wounds on their bodies heal, and in case of loss of tentacles, a new one grows quickly.

[relatablemarine]

Convergent evolution is the evolution of 'analogous' or similar structures in organisms that are not closely related. Such as the wings of insects, birds and bats. One potential example of this is the Diplomoceras maximum, an extinct squid-like creature who is clearly analogous to, or a distant cousin of Clippy the paperclip. This amazing creature lived 68 million years ago, with the most notable fossil found at the cephalopod rich López de Bertodano Formation of Seymour Island, Antarctica. An area that was formerly warmer before further movement of tectonic plates. The fossil shell measured an impressive 1.5 metres and is formed from ridges, speculated to grow a section annually. These ribs are thought be similar to tree rings, being used for dating samples and gaining insight about the environment of the prehistoric sea, such as measuring the carbon and oxygen isotopes in the shell.

🐙Daily Cephalopod Fact:🐙

Chambered Nautilus: The nautilus is an octopus’ cousin. It has more than 90 tentacles — the most of any cephalopod — which it uses to feel and grope along the reefs for food. Unlike those of other cephalopods, a nautilus’s tentacles have grooves and ridges instead of suckers. The nautilus is the only cephalopod with an external shell. Much like zebras, nautiluses can be individually identified based on their striped shell patterns.

March Madness: Bracket 2

Welcome back for another round of March Madness! Today's competitors are Endoceras giganteum vs. Seirocrinus subangularis.

Endoceras has come up before (it was a fossil friday post during the Ordovician talks in January. It is the biggest fossil cephalopod found.

The largest specimen on record is 18 ft long (5.73m).

Seirocrinus, on the other hand is a massive crinoid from Germany. This particular one is 63 ft (18m) long (tall?) Insane, am I right?

Behold the dazzling colors of an iridescent ammonite (Placenticeras intercalare)! A relative of today’s squids, this ammonite lived some 80 million years ago near what is now Alberta, Canada. This fossil’s spectacular coloration is the result of millions of years of high temperatures and pressures. As these forces acted on nacre in this ammonite’s shell, it was transformed into a gemstone known as an ammolite. Along with amber and pearl, ammolite is one of only a handful of gems made by living organisms. You can spot this rare specimen in the Louis V. Gerstner, Jr. Collections Core in the Museum’s Richard Gilder Center for Science, Education, and Innovation!

have you seen ticinoteuthis chuchichäschtli the tintenfischart

«Zuerst haben wir uns überlegt, die Art nach einem Kollegen zu benennen», sagte Christian Klug vom Paläontologischen Institut der UZH gegenüber der Nachrichtenagentur Keystone-SDA. «Aber das Fossil ist so unansehnlich, dass wir das niemandem antun wollten.» Stattdessen tauften sie den Tintenfisch deshalb auf den Namen «Ticinoteuthis chuchichaeschtli».

lil guys of the Ediacaran

the Ediacaran period was around ~635 million years ago, happening before the Cambrian. This time saw the rise of the first group of animals and the oldest multicellular life. The fossil record is sparse due to the fact that the creatures did not have hard shells, which are the thing most easily fossilised.

the Ediacaran biota appeared ~570 million years ago, and are very taxonomically ambiguous, they may relate to some groups, like cnidaria and protozoans, but some have suggested completely new phylums that we do not have today.

the majority of Ediacaran biota were sessile (lacking the ability to move by themselves) and were soft-bodied. many also lacked mouths and a gut.

here are some lil guys!

These frondose fossils are very controversial, considering they appear to be leafy plants, but may very well be anything from animal or protist, to stem fungi (https://www.science.org/doi/10.1126/science.1099727)

this is an Erniettamorph and we know basically nothing about these! The fossils were found in places where photosynthesis would not have been possible, and one type of these fossils has been found with the tubes completely covered and filled with sand, which makes the possibility of osmotic feeding from the surrounding water difficult as it would reduce the metabolically active volume. (https://www.pnas.org/doi/full/10.1073/pnas.0904836106)

Dickinsonia is a more studied animal. and it probably was an animal, due to cholesterol molecules found in fossils. Fossils range from millimetres to ~1.4 metres, and have near bilateral symmetry and rib-like segments. They were a mobile creature and ate microbial mats (trace fossils have been found which are most likely impressions from feeding) (https://doi.org/10.1017/S175569102300004X) A study from 2022 has suggested that they temporarily stuck themselves to substrate with mucus, which suggests a life in shallow waters (https://doi.org/10.1017/S0016756821000194)
