Alternative combination: Leptolepis schoewei. Taxonomy taken from NMNH Catalog Number USNM V 17903. DIAGNOSIS after Schaeffer & Patterson (1984): "Middle Jurassic teleostean fishes of leptolepid grade, but differing from similar fishes in having only chordacentra until late in growth. The chordacentra receive perichordal additions only in the midcaudal region, and only in the largest specimens. About 50 vertebrae, 30 abdominal. Dorsal fin in the middle of the back with about 16 rays; anal originates beneath posterior edge of dorsal, with about 14 rays; pelvics beneath dorsal o

The weather has been so accomodating lately, that I figured that the snow should be gone by now from the slopes of the Wutach area in southwest Germany. I'd been thinking about a particular spot in the Middle Jurassic Callovian and decided to spend some time there. Sure enough, the snow was long gone, so I could scramble down the slope to the site. There are a few other local collectors who visit this site fairly regularly, but it was obvious that no one else had been there yet so early in the season. So I first made a quick inspection tour and found a few blocks which had weathered out over t

Hey everyone! Continuing from the other ID thread, I’d like to hear your opinions on another recent acquisition from the Oxford Clay: a group of associated metriorhynchid teeth. Now, there are several metriorhynchid taxa described from the Oxford Clay Formation: Gracilineustes leedsi, Ieldraan melkshamensis, Suchodus brachyrhynchus, Suchodus ?durobrivensis, Thalattosuchus superciliosus, and Tyrannoneustes lythrodectikos. Pretty much all of them have decent descriptions of their dentition available, so comparing these teeth to the literature facilitates the

Found loose and already broken at Cayton Bay Scarborough. Matrix of ooliths about 0.4mm. Grid of 1cm squares Referred to plate 33:2 in British Mesozoic Fossils, Natural History museum, British Museum. Plate Very similar to my find except that the rate of increase in whorl fattening is greater than illustrated. Lateral tubercules correct. However every photo I've seen of M. macrocephalus has no tubercules. Is it what I've found in the book? The book was published in 1975.

I guess as you get older, you get a little more crazy. I had sworn to slow down a bit, particularly after my exhausting hike down the mountain recently, so I'd been visiting easy-to-work sites like the ditch and the shark tooth exposure the last few weeks. But then my colleague told me that he'd opened up another section at the Callovian site in the Wutach Valley and that I should have a look at it. Maybe you can make some good finds. Well, why not? So off I went today. At this site you have to remove a lot of overburden to get at the good horizons and then you're whacking away at a hard

From the album: Middle Jurassic Ammonites from Southern Germany
3.5cm. This specimen with its shell mostly intact shows the innermost whorls of this subspecies. The venter at this stage is flat, but it rounds off at a later stage and gets covered up as it grows. From the koenigi zone, lower Callovian. Found in the Wutach area.-

We're still allowed to move about freely here in good old Baden-Wuerttemberg, so I figured as long as this is still the case, I'll mosey along to my spot in the Callovian in the Wutach Valley. A friend of mine has been working there recently, so I was hoping for some more fresh exposure and sure enough, he'd opened up some new possibilities for me. Spent the good part of the day prying and hammering and came up with a few nice things. Here's the first and probably the best which I just finished prepping this evening. A multiblock measuring 12x12x6cm with 4 x Choffatia sp. and a bit of belemnit

Hi all, Last part of my finds of the year. In autumn, between lockdown 1 & and lockdown 2, we managed another 3 days hunts. First day was spent in our usual trilobites spot, which happened to be on the way to our main destination this time. You have already seen in my first part some of the trilos we did find on that day, which was a rather good one for me. Day two was spent in Nanteuil quarry not far from Niort. the quarry got mostly bajocian and aalenian. the aalenian is on the "ground of the quarry" and was mostly drown at that time of year. So Bajocian- 3 replies
