found this on the beach near Lourhina, Portugal. Fossils in the Lourhina Formation are late Jurassic. This looks like a small walnut but the unusual shape with a cleft in the face isn't like any walnut. I can't find it in fossil botanical books.

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.- 7 replies

I recently saw this therapod indet. tooth for sale from the Lourinhã formation, Portugal. It measures 21.99mm x 10.40mm x 3.78mm. How does it look and are those lines cracks/wear or natural? Also does anyone have any idea on the ID? How is the quality and should I consider buying it or pass it on?

Could someone please ID these therapod teeth from the Lourhina formation? All are kimmeridgian and around 2cm. No. 2 is described as allosaurid, lourhinasaurus?
