Pathological Megalodon Tooth-3 Sides of Serrations
meg.cu posted a topic in General Fossil Discussion
Has anyone seen this before on a pathological megalodon tooth. I am thinking of buying this tooth from a friend and wanted to hear what the shark to professionals think. Sorry for quality of pictures, I'm waiting for better.- 16 replies

Collection Additions From The Miocene And Oligocene Marine

Hey Guys, Thought I would start a thread showing some of the more notable finds lately. These are 2013 finds so far. Since there are several pictures, it will take a few posts within this thread. I have to say that most my dives don't include unusual finds. You have to go through a lot of more common material before you find some nicer stuff. I hope you enjoy! Jason This first is a grouping of nicer C. angustidens with the biggest being a little over 4".- 23 replies

I picked up this odd vertebra in a stream environment in Austin, TX. It is missing one of the posterior transverse foramina altogether, and shows asymmetrical processes between left and right sides. I am unable to articulate any other pathologies other than to say it just ain't right. So, is this canine? Is the pathology likely the result of a defect from birth? Any thoughts appreciated.

Wondering if Mosasaur get pathological teeth like in sharks & megs? I got these teeth recently and I notice they look a little strange - they look kind of twisted and strange unlike other Mosasaur teeth I have come across. Any idea, if these are pathological or are they just from a certain genus with weird-looking teeth?

The palaeoenvironment of Monte Bolca Lagerstätte was reconstructed as a basin or a sub-tropical lagoon, close to land and connected to rivers and wetlands. This basin showed phases of opening to the sea and phases of enclosure and isolation. During the "closed" phases, living conditions such as high(er) salinity and low(er) oxygen content in the bottom explained the exceptional conditions of fossilization and the absence of benthic fauna and scavengers. Worsening living conditions could also result in a higher percentage of fish infected by parasits. Their presence should reflect an unbalanced palaeoenvironment in the basin where the fishes of the "Pesciara di Bolca" fossilized. The collection of fossil fishes from Monte Bolca (Eocene of Northern Italy), deposited at the Museum national d'Histoire naturelle, Paris, was examined by Gilles Petit for the detection of parasites or traces of their activity. Of the 349 fishes studied, 62 showed a fairly well-preserved integument for the observation and 9.6% out of them showed skin-nodules. I am not sure, but I think this Pseudosparnodus microstomus had the same problem: Here is a close-up of it's ventral and abdominal region showing several skin nodules (at least that's what I believe): This is a close-up out of G. Petits original paper: And this is a living species with skin nodules (also out of G. Petits original paper): Here is the original paper from G. Petit Thomas
