DISCOVER PANAMA FOSSILS OF HISTORY ON THEM, Megalodon chronospecies ?

Megalodon chronospecies ?
In the last class before they Paleontology Independence Day in Panama which excites me a lot, there was much talk about sharks last where Professor Pepper has much knowledge about it .

In the Gatun Formation ( about 10 Ma ) , there are 15 locations including: San Judas near future where we have been , Payardi third set of locks , etc. . In San Judas a depth of about 25 m but in other localities of this formation reach 100 m are presented .

Gatun Formation ( St. Jude )

Regarding the Culebra Formation ( ~ 20 Ma ) Early Miocene are more vertebrae that outcrop along the Panama Canal . A curious fact is that if the vertebrae calcify . In this formation almost all fossils are broken a good hypothesis of this would be that they are fossil re transported have been dragged in several places causing them these wear even because before that site was a delta where there was a lot runoff ( stream waters ) .

It is very important to know that if you see a shark tooth shark sacramental not died in that place because as we know sharks have the ability to replace the missing tooth on the other by the other rows of teeth posing in the back, but if they are then vertebrae is different then the shark must have died in that place.

Megalodon teeth are enormous compared to existing tooth sharks within the findings of said teeth found teeth 20 cm total length and 16 cm in height, these teeth are often found in the Gatun Formation and we have seen in the town of St. Jude, but that site only has been observed not very big teeth because it is presumed that this place was a shark breeding area for 3 evidence :

The depth is very shallow ( shallow )
Findings tiny shark teeth ( but are not post anterior teeth )
Productivity was very good ( food)

Note that a breeding area may be shared by several species.

We talked a little about Cope ‘s Rule tells us : The more Greatest Time .

Much megalodon tooth compared with the White Shark ( Carcharodon carcharias ) in which their teeth are 4 cm high.

Megalodon is chronospecies : it is a species that change morphologically and genetically in evolutionary time scale but by lineages or descendants , the original species never existed in the same time species derived .

Importantly, in geological time in the Pliocene the megalodon tooth cusps were more attached to the central tooth , but in the Oligocene were more separated .

Shark body size in Time

The question to ask is : Are They reached the maximum size ( Megalodon ) before dying ?

Know that Coprolites are fossilized feces and proves its importance because it helps us to :

Discover eating habits
Predation of extinct species

Distribution of species abundance THROUGH geologic time

Regarding this topic expert John Ortiz told us many important aspects about micropalaeontology that above refers to micron diameters agency and not a party; examples : pollen , spores, foraminifera , dinoflagellates , diatoms )

Three important aspects of this issue are:

Dsitribución Space
time
abundance

We spoke of Petroleum Industries where used much paleontology for obtaining accurate soil where they extract oil ( black gold) through where the area estratigrafñia and exclusive fossils in each stratum manage to get the underground floor is located the black gold.

I found it extremely important to ask about How do you know that area must dig to find oil? and his response was excellent told us the Oil Industry has millions of dollars intended to investigate that what they do is : draw a picture through energy using Explosion which is called Seismic Prospecting, able to know if the area is suitable for start the day for oil .

Last but not least we spoke of many statistical programs that are free and help many different research projects that we have biologists for example :

R Project for Statistical Computing
my SQL
GPlates
GRASS GIS

I enjoyed listening to future research topics of Professor Catalina Pimiento since it would be extremely important to know those aspects of Megalodon , as you will save a great respect for sharks and dedicate myself to know them now , but you help us known them in the past, incited people to get into this world of sharks is extremely fascinating as we once said the teacher July Lamilla (Chile ) they are the policemen of the sea and maintain order and the balance .

I found it very interante true class and I am sure all my colleagues and I acquired new knowledge. The only question is whether I was in Panama found Coprolites ?
