Macronaria indet (Tooth of Sauropod)

Brief explanation...

From an abstract: For some time it was my desire, to bet on a section dedicated to the Dinosaur fossils of the Upper Jurassic of Portugal. Unfortunately for lack of time and fossils for sale, it has led me to postpone that bet on my site successively. Time has got, the fossils are still very scarce... The few fossils I am arranging, as a rule I sell directly, to some of the greatest collectors of the World.
For over 20 years I have been traveling through many sites in Portugal to collect fossils from various geological periods. Collecting Dinosaur fossils, along this coast of Portugal by the sea, with large slopes and high cliffs, is a great challenge and a high security risk. Only the most crazy ones venture out on these dangerous adventures. I am one of those few crazy who do it with great pleasure..
Occurrence of fossils in Portugal: is very evident in almost all regions, particularly along the coast. Here, can find some of the biggest fossil deposits, distributed by various geological periods. Much of the best fossiliferous deposits are becoming less accessible, some have simply disappeared. Urban sprawl has greatly contributed to this fact, particularly along the coast. The neglect of non-preservation of these areas is another problem that has contributed to its gradual disappearance. The rapid erosion in recent years, in some platforms fossil cliffs on the shoreline navy has also aggravate your disappearance regressive form of this irreplaceable paleontological heritage. It is increasingly difficult, finding good specimens of fossil species in Portugal. Many species are virtually impossible to get back to be collected, some are only possible to see in old private collections or museums.
It is not easy to find good dinosaur fossils, in Portugal. Many of these circumstances are due to the geographical characteristics and urban development of Portugal. Portugal, is a small country, the main fossiliferous platforms are hardly accessible and in many cases currently, completely inaccessible to collect fossils.
Although the Jurassic formation of Lourinhã - (in Portugal) is similar with the formation of Morrison - (in North America), or the Formation of Tendaguru - (in Tanzania), the geography of both formations are completely different, in aspect and size. All these facts, make it very difficult and dangerous to collect and find good fossils of Dinosaur of the Upper Jurassic in Portugal...
The work of preparation: All my fossils are prepared by me. I'm not the big expert, but I have some good enough knowledge to be able to venture into that area as well. I am currently a volunteer preparer at the Lourinhã Museum. Also I contributing with some fossils, to the Museum collection.
All the fossils prepared by me, are simply cleaned and solidified. No, I am nothing adept at falsification or over artificial arrangements. All my fossils are 100% mineralized fossils. No, plastic parts, or other matters... who buys me a fossil, may have absolute assurance that this is buying a fossil, in the condition of fossil and not a piece of anything else. After selling any fossil, each one is free to do what he understands with the same. I do not criticize or support, the dicision of each. Only, I am not a great adept of perfection, in something that is hardly perfect after millions of years, until it is found and collected.
Neither will I be classifying my fossils, with exotic classifications, whose sole purpose is simply to sell "cat by hare" and get some additional value. To the best of my abilities, I will only focus to add to the information of the fossil, the genus. And, only when I have enough information can I add the name of the species, which corresponds to the fossil.
Here is the opinion of a great american collector, of Dinosaurs of the Jurassic in The fossil forum: "Everyone will have a different definition of what an exotic tooth is depending on the level of their collection. I have been collecting for over twenty years and my experience is mixed and would raise the caution flag with online purchases. First like Regg stated a number of dealers use exotic names as a marketing tool to sell teeth for profit. Unfortunately eBay is filled with this technique. Other dealers simply accept what is told to them when they purchased the item for resale and are happy to do so because of the upside. Dinosaur teeth can be very difficult to ID and I hate to say it but very few dealers can adequately do it. You have to become well versed in what you are buying and become an expert. You also have to get to know the dealer and find out where he obtained the tooth, who ID it and if you can return the item.

To answer the initial question my experience is that most real exotic teeth rarely make it to the public market. Most reputable dealers have a listing of their favorite clients and will contact them as soon as they obtain a specimen."



Rare fossils of Portugal

About the fossils of Portugal

Fossils of Portugal: specimens of several species presented here are fossils caught, selected and prepared by us, some specimens are part of my private collection. Having as to meet demand and interest from some discerning collectors worldwide.

Classification: The specimens are sorted by species (where possible), where they were caught and degree of rarity.

Uncommon - Rare - Very rare and extremely rare.

The degree of rarity is associated with the occurrence of species in Portugal and perfection of the specimens submitted. Possibly some of the rare species in Portugal, may be common in any other part of the world... classification of rarity has sole discretion as to my experience as a collector of over 20 years dedicated to collecting fossils, the most varied places of Portugal. Not probably, this ranking official scientifically...

The fossils presented in this gallery are exclusively being sold.

Thank you very much for your attention and for visiting my website.


Dinosaurs of the Lourinhã Formation:

In a 2003 study, an analysis of all Portuguese dinosaurs was published. The study created a cladogram showing the possible relations of all Portuguese dinosaurs, including those at the time known from the Lourinhã Formation.[4]
