Do you remember in my last post when I visited the beautiful region of Sesimbra? I mentioned that there was a very important path since there were dinosaur footprints of various species! My post today is a research post, basically I went into the Portuguese coast in search of dinosaur footprints, for which I had to carry out a pilot investigation of the areas that had records of preserved footprints! It is the first time that I do this activity and it was something unique. I hope you enjoy my discoveries and information!🧠🦖
Recuerdas en mi post pasado cuando visite la hermosa region de Sesimbra? mencione que habia un sendero muy importante ya que habian huellas de dinosaurios de varias especies! mi post de hoy es un post de investigacion, basicamente me adentro en el litoral Portugues en buscas de huellas de dinosaurios, para el tuve que realizar una investigacion piloto de las zonas que tenian registros de huellas preservadas! es primera vez que realizo esta actividad y fue algo unico espero disfrutes de mi descubrimientos e informacion!👨🏫🦕🕵️♂️

The Cape Espichel area is known for being an area with strong erosion activity, the large rocks in the area suffered erosion by water and wind for millions of years giving different shapes and colors, this phenomenon of erosion in the rocks along with the movement of The tectonic plates give evidence of tracks with more than 150 million years very well preserved, more than a thousand tracks have been discovered in total of different species of both carnivorous and herbivorous dinosaurs, but why was this area so active?💡😮
La zona de cabo espichel es conocida por ser un area con fuerte actividad de erosion, las grandes rocas del area sufrieron durante millones de años erosiones del agua y el viento dando formas y colores diferentes, este fenomeno de erosion en las rocas junto al movimiento de las placas tectonicas dan evidencia de huellas con mas de 150 millones de años muy bien preservadas, se han descubierto mas de mil huellas en total de diferentes especies de dinosaurios tanto carnivoros como herbiboros, pero porque esta zona tuvo mucha actividad???🕵️♂️💧🦖🌄🌊
This area presents great evidence of dinosaur activity because approximately 130 million years ago in Portugal this was the only area that had an ecological interaction with the sea, therefore, since there was an aquatic habitat, it was assumed that the animals would move in these areas. in search of food and shelter, due to the conditions of the land whose property is clay there is a greater erosion activity so that more than 100 years ago it was an area with land the erosion of the sea turned it into a cliff revealing the layers of the stones!🤔😮
Esta zona presenta una gran evidencia de actividad de dinosaurios porque hace 130millones de años aproximadamente en Portugal esta era la unica zona que tenia una interaccion ecologica con el mar, por tanto al exister un habitad acuatico era de suponer que los animales se desplazaran en estas areas en busca de alimento y refugio, debido a las condiciones de la tierra cuya propiedad es arcillosa existe una mayor actividad de erosion por lo que hace mas de 100 años era una zona con tierra la erosion del mar la conviertio en un acantilado revelando las capas de las piedras! 🦖🦕
While I am walking the path I am photographing the ecological conditions of the area and it strikes me that we see a vegetation with many bushes and few trees, but at the same time I thought that this probably had a very different environment there would be trees many meters high because there were herbivorous dinosaurs with very high necks, and in the blink of an eye I realize how the earth evolves in such different ecologies over the years! recently in 2021 it was possible to discover in this area some traces of crocodilomorphs, that is, very primitive crocodiles🤯🕵️♂️
Mientras realizo el sendero voy fotografiando las condiciones ecologicas de la zona y me llama la atencion que vemos una vegetacion con muchos arbustos y pocos arboles, pero al mismo tiempo pensaba que esto probablemente tenia un ambiente muy diferente habria arboles con muchos metros de altura porque habian dinosaurios herbiboros con cuellos muy altos, y en un abrir y cerrar de ojos me doy cuenta como la tierra evoluciona en ecologias tan diferentes con el pasar de los años! recientemente en el 2021 se logro descubrir en esta zona algunas huellas de unos Crocodilomorfos osea cocodrilos muy primitos 🌍🌅
Exactly 130-136 million years ago in the Lower Cretaceous it is believed that animals walked these lands, the research area where I am going is called (Jazida dos Lagosteiros) this is my first stop here if I am lucky I will be able to see a footsteps of one of the dinosaurs that dominated the Portuguese lands, the Allosaurus, was a powerful and agile carnivore that dominated the coastal littoral and whose prey were other herbivorous dinosaurs🦖😮
Exactamente hace 130-136 millones de años en el cretacico inferior es que se cree que los animales caminaban estas tierras, el area de investigacion a donde me dirijo se llama (Jazida dos Lagosteiros) este es mi primera parada aqui si tengo suerte podre ver una pisadas de uno de los dinosaurios que dominaron las tierras portuguesas el Allosaurus, fue un poderoso y agil carnivoro que domino el litoral costero y cuyas presas eran otros dinosaurios herbiboros💥

I reached my first point where I would look for the first signs of dinosaurs and of course I was lucky because I was able to recognize the footprints of a tetrapod, in this case the imposing Allosaurus fragilis, how do I know what a tetrapod footprint is? bibliographical references tell us that a tetrapod with a footprint with three pointed fingers, these animals were scientifically known as tridactyls! Luckily I didn't have to run into a live one because they are more than 7 meters long and weigh 4 tons, only the femur of the animal was 2 meters high.😮😮
Llegue a mi primer punto donde buscaria los primeros indicios de dinosaurios y claro tuve suerte porque logre reconocer las huellas de un tetrapodo, en este caso el imponente Allosaurus fragilis, como se que es una huella de un tetrapodo? las referencias bibliografica nos dice que un tetrapodo de una huella con tres dedos puntiagudas, estos animales eran conocidos cientificamente como tridactilos! menos mal no tuve que toparme con uno vivo porque tienen mas de 7 metros de largo y pesan 4 toneladas, solo el femur del animal tenia 2 metros de altura.🦴🦿🦾
*If we see the first finger from right to left, it complies with the description of a tetrapod, the three pointed fingers, despite the fact that the footprint is not very well preserved, we can imagine a little what its footprint was like and its size.🕵️♂️🦖🦕
Si vemos el primer dedo de derecha a izquierda cumple con la descripcion de un tetrapodo los tres dedos en forma puntiagudos, apesar de no estar muy bien preservada la huella podemos imaginar un poco como era su pisada y el tamaño de la misma😮😮
🦖🕵️♂️LIVE THE EXPERIENCE WITH ME / VIVE CONMIGO LA EXPERIENCIA🌍🧭
I have to admit that it is such a brutal experience to be able to travel millions of years to see the footprint of an animal that ruled our lands and that was probably at the top of the food chain and had no competition on earth!😮😮
Tengo que reconocer que es una experiencia tan brutal poder viajar millones de años para ver una pisada de un animal que goberno nuestras tierras y que probablemente estaba en lo mas alto de la cadena alimenticia y no tenia competencia en la tierra! 🦖🦕

I continue with my research and now we go to the traces that were revealed by the erosion of environmental factors, water and air, and we can see how there are now clearly footprints of Sauropods, they walked the plains of Portugal more than 145 million years ago , here there is a lot of interesting information to highlight, due to the size of the footprints they were young, they measured between 1.5-1.8 meters only from the haunch, their behavior tells us that they could not run and that they walked at 3.4 km / h- 4.1km/h🤯🌅
Continuo con mi investigacion y ahora pasamos a las huellas que fueron reveladas por la erosion de factores ambientales, el agua y el aire, y podemos ver como ahora hay claramente pisadas de Sauropodos, ellos pasearon las planicies de Portugal hace mas de 145 millones de años, aqui hay mucha informacion interesante para resaltar, por el tamaño de las huellas eran jovenes, median entre 1,5-1,8 metros solo de anca, su comportamiento nos dice que no podian correr y que caminaban a 3,4km/ h-4,1km/h🤔🤔🦴🦖
Impressive right? how you can see a young sauropod walking in one direction, and not only is it alone, the data reveals that as they moved in groups they were gregarious animals, another clue reveals that there were some 2.8 meter haunches🤔🤯🔭
Impresionante verdad? como se pueden observar un joven sauropodo caminando en una direccion, y no solo esta solo los datos revelan que como se desplazaban en grupos era animales gregarios, otra pista revela que habian unas pizadas con 2,8metros de anca📕📖

And if I tell you that my adventure does not end here yet? and that I will travel about 15km to a nature reserve in search of more tracks? but these footprints are different!!!...😍😍
Y si te digo que mi aventura aun no termina aqui? y que me desplazare unos 15km hacia una reserva natural en busca de mas huellas? pero estas huellas son diferentes!!!...🤯🤔

In this last area I investigate the most preserved footprints that I saw, they were discovered by some workers who worked extracting rocks in a quarry, noticing that the footprints on the stones had symmetry, they thought it was the record of an animal, but they had no idea what they had discovered footprints with 155 million years, here we date that the animals were from the Upper Jurassic it is believed that there was some body of fresh water in the area so more than 100 footprints could be discovered😮😮
En esta ultima zona investigo las huellas mas conservadas que vi, fueron descubiertas por unos trabajadores que trabajaban extrayendo rocas en una cantera, al notar que las huellas en las piedras tenian simetria pensaron que era el registro de un animal, pero no tenian idea que habian descubierto huellas con 155millones de años, aqui datamos que los animales eran del jurassico superior se cree que habia algun cuerpo de agua dulce en la zona por lo que se pudieron descubrir mas de 100 huellas👨🏫👨🏫
🚙🦖🔭HOW ARE FOOTPRINTS FORMED?/ COMO SE FORMA LA HUELLA (ES)🌍🧭
In this video I explain what we see in the rock and also how the movement of the tectonic plates reveals the traces that have been covered by other layers of earth! it seems that the dinosaurs climbed the walls but when the tectonic plates exert pressure the innermost layers in the earth rise leaving the traces exposed on the surface🤔😮
En este video explico lo que vemos en la roca y tambien como el movimiento de las placas tectonicas revelan las huellas que han sido tapadas por otras capas de tierra! parece que los dinosaurios treparan las paredes pero cuando las placas tectonicas ejercen presion las capas mas internas en la tierra suben dejando las huellas expuestas en la superficie😏😏
I hope that, like me, you have enjoyed this great adventure and learned a lot about how footprints are revealed in rocks, as well as how we discovered clues about the behavior of some dinosaurs! thanks for your support!🙂🙂
Espero que al igual que yo hayas disfrutado esta gran aventura y aprendido mucho sobre como se revelan las huellas en las rocas, asi como tambien descubrimos pistas sobre el comportamiento de algunos dinosaurios! gracias por tu apoyo!😍😍
