La maldición del cocodrilo de Ricla SD
Nov 14, 2022
They have accompanied humans since the dawn of history
Being feared and worshipped for their primitive appearance
which recalls a time when mammals did not dominate the earth
But have crocodiles really changed either
The answer is not found in history books but much further back
165 million years ago the agricultural town of Ricla was a shallow sea
In it lived bivalves ammonites mollusks and other astonishing animals
But it was by no means a calm sea
In it lived predators including a strange crocodile that looked like a dolphin
For years the secrets of this fearsome Jurassic predator were on the verge of being lost to oblivion
This is the story of a curse and the perseverance of a few researchers who fought against it
The curse of the Ricla crocodile begins at the moment of its discovery
In 1994 a major change was about to shake the town of Ricla
The Ricla crocodile was almost run over by the bird
But the paleontologists managed to rescue its skull at the last moment
In previous exploration campaigns before the high-speed rail works
They found nodules in which small bone fragments were visible
Intrigued they decided to take them to the university
Once in the lab the remains waited their turn to be prepared The
process of cleaning and preparing fossils is always long and costly
Sometimes it is necessary to use different methods both mechanical
and chemical until the remains reveal the truth they are hiding
Once again the crocodile's curse complicated things The
nodules were much harder than the bones they contained
And his preparation stretched over time
But the hard effort was worth it
Little by little the pieces fit together to form a skull
But the overall appearance was unsettling
It was undoubtedly a marine reptile and
many specific aspects of its skull resembled those of crocodiles
But was it really a crocodile
What is a crocodile
Everyone knows it's a crocodile although the truth is none of us really know what a crocodile is
The image we have in mind is of a group of a four-legged
animal with short legs a long tail and a flattened head
And that fits very well with the image of modern crocodiles
Crocodiles belong to a group of animals that we call archosaurs
Within this group of archosaurs in addition to
crocodiles there are also dinosaurs and pterosaurs
What are the famous prehistoric flying reptiles
Current crocodiles are all amphibious in their lifestyle That is
they spend much of their time in water but they can also live on land
In fact all the eggs are laid on land and the first
thing a crocodile sees when it is born is the land
So many questions caused the crocodile to be kept away in the museum for a long time
The curse even extended to the researchers who set out to study it
There were several failed attempts to discover what kind of crocodile were facing
Would someone be able to break the curse
I didn't really know what they were talking about
I started studying the crocodile and didn't even know its reputation
It was not yet clear what scientific importance it would later have
And suddenly people started telling me about the curse to be careful with the crocodile
Then it was when I started to find out about the story that this fossil was carrying on its back
The crocodile group to which Rikla's crocodile
belongs were fully adapted to aquatic life
Then they had a set of characteristics that are
not seen in other crocodiles like those we have now
It seems that crocodiles are a much more diverse group than we thought
A tree whose roots are anchored more than 200 million years ago
and of which only a small sample of its last branches has survived to our days
But what was that diversity really like
Crocodiles today although a very popular
animal can be called living fossils
Only small remnants of groups that were once very diverse remain
They emerged at the end of the Triassic about 220-230 million years
ago around the same time as the dinosaurs
And throughout all that time there has been a lot of diversity and different
lineages and only a small fraction of all those lineages remains today
They managed to conquer ecological niches that later they have not been able to achieve
An example is the marine environment another example were
crocodiles that were not carnivores but were insectivorous crocodiles
Even it has been proposed that they were plant-eaters that is they
formed a complex group that existed both on land and in the sea
and part of the marine environment they managed to conquer all ecosystems
but never the aerial ecosystem
For now at least it is not known that crocodiles could fly
The Ricla crocodile is characterized among other things
by having a very long and thin face with a lot of teeth
a bunch of small teeth
then with these teeth that fit perfectly together
It could catch fish fast and small prey
meaning it would have a fish-eating diet
The eyes are another key feature of this crocodile
Unlike modern crocodiles which have their eyes on the top of their
skulls this crocodile would have them completely sideways and very large
That is it would also make it easier for them to see underwater
They had fins instead of legs
They also had a long tail very similar to that of sharks
which would help them propel themselves through the water
What's most impressive well the first thing is that it's a new genus and species
there is no other crocodile like this in the world at least for now
What does the specimen the individual the taxon the most primitive one represent
that is it would be the first in its lineage
It is very important because until now in Spain
there had not been such a complete marine crocodile
After nearly two decades the curse has finally been broken
First the crocodile was rescued from the bird's path
Second he managed to be freed from the rock that was hiding him
Thirdly he found someone who was his equal and could study him
But the paleontologists didn't want this curse to be
forgotten so they engraved it forever in their name
The cursed crocodile of Ricla the maledictus of Ricla
The cursed
crocodile of Ricla
Goodbye crocodile
After the crocodile
Goodbye
That's all Goodbye
