Possible Lourinha Portugal Marshosaurus-like Megalosaurid Tooth
Kikokuryu posted a topic in Fossil ID
I recently purchased a Theropoda indet. tooth from the Lourinhã Formation of Lourinhã, Portugal. I wasn't expecting much initially since it looked like an incomplete tooth and the seller tends to go the safe route with their IDs if it's too vague. But, the serration count was similar to that of the Marshosaurus-like megalosaurid teeth based on @Troodon's guide on the dinosaurs of Portugal. Maybe it's just wishful thinking, but I wanted to see if anyone else had some input before I slap that good old theropoda indet. label on the display. The distal serrations is split down the middle. Mesial serrations were kind of hard to count, but they are at least 20/5mm, the distal serrations are 16/5mm. Not sure if the split serrations are messing with the count, but it should be around that 16/5mm after counting it multiple times with various pictures. I don't know how much further the tooth would have gone had it been complete, but I think the mesial serrations do appear to end before reaching the base. Although I don't know if those serration densities still overlap with other theropods like Allosaurus. Split distal serrations and shape of the base which could be slightly off due to the split serration. Distal serrations. Mesial serrations. Mesial serrations ending? Close up on denticle shape on distal side.

This little fellow is so small that I had to photograph it under the microscope. It's amazing that I found it at all. They don't get much bigger than this apparently. One of the dwarves under the ammonites. This is the microconch to Cymaceras guembeli.
